Coastal Mermaidcore Summer Outfit | Starfish Accessories & Crochet Bag Inspo
There is something endlessly romantic about the idea of dressing like you belong to the sea. Not in a costume-y, over-the-top way, but in that soft, effortless way that makes people stop and ask where you got your bag or how you managed to find earrings that look like they washed up on the shore just for you. That is the essence of mermaidcore — the aesthetic that has been quietly building momentum for the past few seasons and has now officially arrived as one of the most beloved coastal fashion movements of our time.
This summer, mermaidcore is getting a particularly grounded, wearable update. Instead of full sequin dresses and literal shell bras, we are talking about a blended look that draws from coastal living, vintage beach town charm, and a deep appreciation for ocean-inspired textures. Think crochet everything, starfish and shell accessories, shimmery fabrics that catch light the way the water does at golden hour, and a color palette pulled straight from the tide pools — sandy neutrals, seafoam green, pearl white, ocean blue, coral, and soft lavender.
If you have been building a summer wardrobe this season or just find yourself drawn to the ocean in everything from your home decor to your closet, this post is going to feel like finding your people. Let’s break down how to build a full coastal mermaidcore outfit from top to bottom, with a focus on starfish accessories and the one piece that ties every look together beautifully — the crochet bag.
What Is Mermaidcore, Really?
Before diving into specific pieces, it helps to understand what mermaidcore actually means as a fashion aesthetic, because it is more nuanced than the name suggests. At its core — pun absolutely intended — mermaidcore is about channeling the beauty, mystery, and texture of the ocean through clothing and accessories. It blends the natural world of the sea with femininity, vintage sensibility, and a touch of fantasy.
What sets mermaidcore apart from, say, basic beach fashion or nautical stripes is its attention to detail and texture. It is not just wearing blue. It is wearing blue that shimmers. It is not just wearing seashells. It is wearing shells arranged in a way that feels intentional and artful. Mermaidcore also has a strong DIY and artisanal undercurrent — crochet, macramé, hand-beaded jewelry, and vintage finds fit perfectly within its visual language.
The coastal mermaidcore variation we are focusing on today leans into the relaxed, livable version of this aesthetic. It is beachside brunch ready, boardwalk approved, and versatile enough to take from afternoon to evening with a few small changes. It is the kind of outfit that feels like a whole vibe without requiring you to overthink it.
Building the Foundation: Clothes That Channel the Sea
Every great mermaidcore outfit starts with a strong base, and this summer there are so many beautiful options that align with the aesthetic without going full costume.
Crochet Cover-Ups and Tops
Crochet is arguably the single most important textile in the mermaidcore wardrobe right now, and for good reason. The open, woven texture of crochet mimics the look of fishing nets and sea foam in a way that feels completely organic. A crochet top — whether it is a halter, a cropped pullover, or a wrap-style piece — instantly reads as coastal and elevated at the same time.
This summer, look for crochet tops in natural cream or off-white, which feel effortlessly beachy, as well as in seafoam green and soft coral. These shades connect to the ocean color palette without being too literal. If you find a crochet cover-up with shell or starfish motifs worked directly into the pattern, hold onto it like it is treasure, because that is exactly the kind of detail that makes a mermaidcore look feel intentional.
Pairing a crochet top with a flowy midi skirt in a complementary shade is one of the most versatile coastal mermaidcore combinations you can put together. A white crochet halter top over a seafoam or sage midi skirt, for example, looks absolutely beautiful and feels perfectly balanced between beachy and polished.
Shimmery and Silky Fabrics
Mermaidcore is not shy about a little shimmer. That said, the way shimmer is used in the coastal version of this aesthetic is more restrained and natural-looking than full disco-ball sequins. Look for fabrics with a subtle iridescent quality — certain satins, charmeuse silks, and fabrics woven with a hint of metallic thread catch light in a way that feels oceanic rather than flashy.
A slip dress in pearl white or pale lavender with a slight sheen to the fabric is a perfect mermaidcore summer staple. Layer it under a crochet cover-up for a more casual daytime look, or wear it on its own for dinner, dressed up with the right accessories. The juxtaposition of the delicate shimmer with natural, handmade-feeling accessories like crochet and hand-beaded starfish jewelry is what makes this aesthetic so compelling.
Flowy Linen and Gauze
Not everything in the mermaidcore wardrobe needs to shimmer or be woven. Flowy linen and gauze fabrics in ocean-inspired colors provide a wonderful grounding effect in a look that might otherwise feel a little too precious. Wide-leg linen pants in cream, sandy beige, or soft blue are an excellent choice, especially for a more practical warm-weather outfit. Pair them with a crochet top and your starfish accessories and you have a complete look that is both chic and genuinely comfortable.
Gauze dresses with tiered skirts and ruffle details are another excellent option. They move beautifully in the sea breeze and photograph like a dream, which is partly why you see so much of this silhouette flooding coastal fashion content every summer.
Starfish Accessories: The Heart of the Mermaidcore Look
If crochet is the texture of the mermaidcore aesthetic, then starfish accessories are its signature symbol. There is something so iconic about the starfish as an object — the perfect radial symmetry, the rough texture, the way it feels like a direct message from the ocean floor. When worked into accessories, it strikes the ideal balance between natural, feminine, and slightly otherworldly.
Starfish Earrings
The easiest and most impactful way to introduce starfish into your outfit is through earrings. Right now, you can find starfish earrings in almost every style imaginable, and each one brings a slightly different energy to a look.
Delicate gold starfish stud earrings are perhaps the most universally wearable option — they add just a hint of the aesthetic without demanding too much attention. They work beautifully with both casual and dressed-up looks and pair nicely with other gold jewelry.
For something with more presence, look for starfish drop or dangle earrings. These are especially lovely in oxidized silver, which gives them an antiqued, found-from-the-sea quality that feels very mermaidcore. A pair of statement starfish earrings with a simple outfit can carry the entire look — sometimes less is more, and letting one statement piece do the heavy lifting is a very elevated styling move.
If you love more texture and dimension in your jewelry, look for enamel or resin starfish earrings that include color — pale coral, sandy gold, or even a pale iridescent finish. These feel playful and modern while still fitting perfectly within the mermaidcore palette.
Starfish Necklaces and Layering Chains
Layering necklaces is a core part of the mermaidcore jewelry strategy, and starfish pendants fit perfectly into a layered look. A thin gold chain with a small starfish charm at the center works beautifully as a mid-length layer, especially when paired with a shorter pearl or shell necklace closer to the collarbone and a longer chain with a sea glass or coral pendant further down.
This kind of layering tells a story — each piece looks like something you collected over time from different beaches and different summers, which is completely consistent with the mermaidcore spirit. The aesthetic is not about matching sets but about curated, personal, meaningful accumulation.
For a bolder statement, look for a beaded starfish necklace worked in tiny seed beads in oceanic colors. These are often handmade, which aligns beautifully with the artisanal soul of the aesthetic, and they make an incredible focal point for a simple crochet or slip dress outfit.
Starfish Hair Accessories
Do not underestimate the power of a hair accessory in this aesthetic. A starfish hair clip or barrette is a small detail that absolutely elevates a coastal mermaidcore look. Wear one on the side of a low bun, clip it near a half-up half-down section of loose waves, or add a small one near the ear for an unexpected touch.
Metallic starfish bobby pins are another subtle option that pays off visually, especially if you have a style where the hair is pushed back and the accessories catch the light. Think about texture and finish when choosing these — matte gold, brushed silver, and pearl-inlaid options all sit within the aesthetic.
Anklets and Toe Rings
The mermaidcore look extends all the way to the feet. Delicate anklets with starfish charms are one of those accessories that feel so right for summer — they are barely-there but perfectly on theme. Layer two or three thin anklets at different lengths for that effortlessly collected look. Shell and pearl anklets mixed with a starfish charm anklet create a beautiful, textured moment around the ankle that pairs perfectly with sandals or bare feet on the beach.
The Crochet Bag: Your Most Important Summer Accessory
Let’s talk about the piece that has become absolutely central to the coastal mermaidcore summer aesthetic — the crochet bag. Whether it is a tote, a bucket bag, a mini shoulder bag, or a crossbody, the crochet bag is the one accessory that can instantly transform an outfit from regular summer to full coastal mermaidcore.
What makes the crochet bag so perfect for this aesthetic is the way it communicates craft, intentionality, and a connection to natural textures. It does not feel mass-produced or trend-driven, even if you found it at a large retailer. There is something inherently handmade-feeling about crochet that aligns with the soulfulness of the mermaidcore aesthetic.
Choosing the Right Crochet Bag
The most popular style this summer is the open-weave tote in natural jute or cotton with shell and bead embellishments. These bags look beautiful when partially packed — a little bit of colorful beach towel or a bottle of sunscreen peeking out adds to the laid-back coastal energy. Look for bags that have shells, pearls, or starfish worked into the design either as pendants hanging from the handles or woven directly into the body of the bag.
Bucket bags in crochet are another wonderful option, particularly for evening looks or situations where you need something a bit more structured. The silhouette has more polish than a tote, and when rendered in cream or white crochet with a drawstring closure and a few shell charms, it looks genuinely elevated.
For a smaller option that works beautifully for evenings out or days when you do not need to carry much, a crochet mini bag in a round or half-moon shape is incredibly charming. These little bags are having a major moment right now, and for good reason — they are adorable, practical enough for essentials, and they make the most delightful photo subject when placed on a sandy surface or a rattan chair.
Color and Detailing
When it comes to color, natural and neutral crochet bags are the most versatile — cream, off-white, natural jute, and sandy beige work with almost every color in the mermaidcore palette. That said, do not be afraid of a seafoam green or a pale coral crochet bag if you find one. These feel so fresh for summer and can become the unexpected color anchor for an otherwise neutral outfit.
Pay attention to the finishing details on any crochet bag you are considering. Wooden beads along the handles add warmth. Shell fringes along the bottom edge are particularly beautiful and move with a satisfying sway when you walk. Woven-in starfish motifs bring the whole aesthetic full circle.
Styling the Crochet Bag
One of the most beautiful things about the crochet bag is how versatile it is. Carry your full open-weave tote to the beach over a crochet cover-up and a breezy linen wrap skirt. Switch to your crochet bucket bag for lunch at a seafood restaurant overlooking the water. Pull out your little crochet mini bag for a sunset walk. The bag adapts to the occasion while keeping you connected to the aesthetic throughout the day.
The Full Coastal Mermaidcore Look: Putting It All Together
Now that we have covered all of the individual elements, let’s paint a picture of what a full coastal mermaidcore summer outfit might look like in practice.
Imagine starting with an off-white crochet halter top — open weave, relaxed fit, maybe with a slight scallop edge along the hem. Pair it with a flowing midi skirt in pale seafoam green, made of lightweight gauze that catches the breeze as you walk. On your feet, flat strappy sandals in tan leather keep things grounded and practical. The flat shoe is important here — platform or chunky shoes pull the look in a different direction, while a flat sandal keeps everything soft and natural.
For accessories, start with your layered necklaces — a pearl choker at the collarbone, a thin gold chain with a small starfish pendant at mid-length, and a longer chain with a sea glass drop. On your ears, oxidized silver starfish drops add a touch of that antiqued, found-from-the-ocean feeling. Thin anklets layered on one ankle, a mix of shells and stars, complete the lower half. Your hair is in loose, slightly wavy natural texture, with a single starfish hair clip tucked near one ear.
Carry a medium open-weave crochet tote in natural jute with shell fringe along the bottom edge. Inside you have your essentials, a light linen scarf that doubles as a wrap if the evening turns cool, and maybe a small bouquet of dried wildflowers tucked in one corner just because it looks beautiful and it feels right.
That is a coastal mermaidcore summer outfit. It feels effortless and intentional at the same time. It tells a story. It looks like it belongs at the edge of the sea, and you look like someone who knows exactly who she is and exactly where she most loves to be.
Where to Shop for Coastal Mermaidcore Pieces
Finding these pieces is genuinely wonderful right now because the trend is peaking just as more independent makers and sustainable brands are producing exactly what the aesthetic calls for. Etsy is one of the best places to find handmade crochet bags and starfish jewelry — you will often find small shops run by artisans who make each piece to order, and buying from them adds to the authenticity and intentionality of the aesthetic.
For clothing, vintage and secondhand shops are gold mines for the kind of flowy, feminine, natural-fabric pieces that form the foundation of a mermaidcore wardrobe. Think about what you already own — a flowy white dress, some light linen pants, a cream top — and consider how accessories and a crochet bag could immediately bring those pieces into mermaidcore territory.
Larger retailers like Free People, Anthropologie, and even some H&M and Zara collections have begun offering mermaidcore-adjacent pieces each season, which makes the aesthetic increasingly accessible. But even when shopping at these larger stores, the magic is in how you combine and layer the pieces — your curation is what makes it mermaidcore rather than just summer fashion.
Final Thoughts
Coastal mermaidcore is more than a trend — it is a way of relating to summer, to the natural world, and to the idea that the most beautiful things are often those that feel like they came from somewhere real and wild. The starfish earring that catches the light at dinner, the crochet bag that smells faintly of sunscreen and sea air, the shimmer of a slip dress at golden hour — these details add up to something that feels genuinely magical.
This summer, dress with the sea in mind. Let the tide pools and the rock formations and the way the light moves across the water inspire your color choices. Invest in pieces that feel handmade and meaningful. Build an outfit that tells the story of someone who loves this earth enough to wear it.
The ocean will be waiting for you, and you will be ready.
