Summer Maternity Beach Outfit | Knit Cover Up + Striped Shorts Bikini Look
There is something undeniably magical about being pregnant in the summer. The warm air, the sound of waves, the feeling of sun on your skin — and that beautiful belly that deserves to be celebrated, not hidden. If you have been scrolling through maternity fashion looking for a beach outfit that actually feels stylish, comfortable, and bump-friendly all at once, you have come to exactly the right place. Today I am sharing one of my favorite summer maternity beach looks: a breezy knit cover up paired with a striped shorts bikini set that makes every beach trip feel like a vacation even when you are waddling to the shoreline.
Let me walk you through the entire look, why it works so well during pregnancy, how to style it, where to find similar pieces, and a few extra tips for staying cool and comfortable all summer long.
Why Maternity Beach Fashion Matters More Than You Think
Before we dive into the outfit details, I want to talk about why putting thought into your maternity beach wardrobe is actually worth your energy — even when you are exhausted, swollen, and living in stretchy waistbands.
When you are pregnant, your body is doing something extraordinary. It is easy to fall into the trap of wearing whatever fits and calling it a day, but there is real value in choosing pieces that make you feel like yourself. Confidence during pregnancy is not shallow. It is deeply connected to how you feel mentally and emotionally during a time that can be overwhelming, beautiful, uncomfortable, and joyful all at once.
A great beach outfit during pregnancy should do a few things: it should accommodate your bump at every angle, provide enough support for an active beach day, keep you cool in the heat, and ideally photograph well so you have memories you will actually want to look back on. This look checks every single one of those boxes.
Breaking Down the Look: The Knit Cover Up
The star of this outfit — and possibly the most versatile piece in my entire maternity wardrobe this summer — is the knit cover up.
When I say knit, I am talking about an open-weave, lightweight crochet-style cover up that drapes beautifully over a bump without clinging uncomfortably. This is not the kind of tight, stretchy knit that shows every curve in a way that might make you self-conscious. This is an airy, relaxed knit that moves with you, lets the breeze through, and creates the most effortless bohemian beach look imaginable.
What to look for in a maternity knit cover up:
The best maternity knit cover ups share a few key qualities. First, look for an open, flowy silhouette — something that falls well below the belly and does not ride up when you sit or walk. A tunic or maxi length works especially well in the third trimester when the belly is at its fullest. Second, the fabric matters enormously. A lightweight cotton or cotton-blend knit is breathable and does not trap heat, which is crucial when you are already running warmer than usual. Avoid synthetic fabrics that do not breathe, because pregnancy already raises your body temperature and the last thing you need is to feel like you are wrapped in plastic at the beach.
Third, consider the neckline. A V-neck or scoop neck is not only flattering on a pregnant figure — it also makes breastfeeding easier if you are planning to wear this cover up into the postpartum months. And trust me, you will want to. The versatility of a great knit cover up extends well beyond pregnancy.
How to style the knit cover up:
Over a bikini at the beach, this piece is obviously perfect. But it also looks incredible thrown over a swimsuit at the pool, worn with maternity denim shorts for a casual lunch in a coastal town, or layered over a sundress on a cool evening. The beauty of neutral and earthy tones — think cream, sand, terracotta, or soft sage — is that they work with almost everything. If you go for a striped bikini underneath, a neutral cover up is your best friend.
The Striped Shorts Bikini: A Maternity Must-Have
Now let us talk about the actual swimwear, because this is where a lot of pregnant women get stuck. Finding a maternity bikini that fits properly, stays in place, and does not make you feel like you are strapped into some kind of medical apparatus is genuinely a challenge. The striped shorts bikini, however, is one of the best possible solutions for summer maternity swimwear — and here is why.
Why shorts-style bikini bottoms work so well during pregnancy:
Traditional bikini bottoms were not designed for a bump. They sit at the hips, which can feel uncomfortable as your belly grows, and they often slide down or bunch up in ways that are both physically annoying and confidence-crushing. A shorts-style bikini bottom — essentially a swim short that sits at or just below the bump — solves almost every one of these problems.
The extra coverage of a shorts bottom means you do not have to worry about adjusting your swimwear every five minutes. It stays put whether you are swimming, walking along the shore, building a sandcastle with your toddler, or lowering yourself into a beach chair. The added fabric also provides a little extra support around the hips and lower back, which is a welcome relief when you are carrying extra weight in the front.
Why stripes are the perfect pattern for maternity swimwear:
Stripes have always been a classic beach look, and during pregnancy they are particularly flattering. Horizontal stripes on a bikini top draw the eye across the body and emphasize the bust, which tends to be fuller and more beautiful than ever during pregnancy. Vertical or diagonal stripes on the shorts create a slimming, elongating effect on the legs. Put them together and you have a coordinated set that looks intentional, stylish, and polished without requiring any extra effort.
Stripes also photograph exceptionally well at the beach. They pop against sand and water, they work in bright sunlight and golden hour light, and they give your maternity photos a timeless, editorial quality that you will love looking back on.
Getting the right fit:
For the bikini top, look for adjustable straps and a clasp or tie closure that can accommodate your changing body. A bandeau-style top can work in early pregnancy but tends to feel insecure and unsupportive as the bust grows. A triangle top with ties is a better choice because it adjusts as you change. Underwire is generally not recommended during pregnancy because it can become uncomfortable as the ribcage expands, but many brands now offer supportive wire-free maternity bikini tops that feel secure without constriction.
For the shorts bottom, a high-waisted style with a soft, wide elastic waistband is ideal. Some maternity swimwear features an over-the-bump panel on the shorts, which provides full belly support and is particularly comfortable in the second and third trimester. Others sit just below the bump, which some women find more comfortable and easier to pull on and off, especially in later pregnancy when bending over is an Olympic sport.
Accessories That Complete the Beach Maternity Look
No beach outfit is truly complete without the right accessories, and the good news is that accessories are the one category of your wardrobe that pregnancy does not complicate at all. Your accessories fit exactly the same whether you are six weeks or thirty-six weeks along, and the right ones can elevate a simple beach look into something that feels genuinely put-together.
A wide-brim straw hat: This is non-negotiable for summer beach days during pregnancy. Not only does a wide-brim hat protect your face and shoulders from UV rays — which is especially important during pregnancy when your skin is more sensitive and prone to hyperpigmentation — it also adds an instant vacation-chic element to any beach look. Pair it with your knit cover up and striped bikini and you look like you stepped off a yacht in the Mediterranean.
Oversized sunglasses: Again, sun protection is your friend during pregnancy. Choose a UV-blocking pair with large lenses that covers your eyes and the delicate skin around them. Oversized frames also balance the visual weight of a prominent bump beautifully, drawing attention upward to your face.
Woven beach bag: A roomy tote in natural straw or woven fabric ties the whole bohemian beach aesthetic together. During pregnancy you are packing more than ever — sunscreen (SPF 50 minimum, and reef-safe if you are swimming in the ocean), snacks because you are always hungry, water because hydration is everything, a swim cover up change, a pregnancy pillow for the beach chair if you have one, and all the usual beach essentials. You need a bag that can hold all of that without looking like a diaper bag before you even have the baby.
Flat sandals or espadrilles: Your feet are almost certainly swollen to some degree, which means high heels or stiff shoes are out. Flat sandals with a cushioned footbed are the way to go. Look for styles with adjustable straps so they can accommodate any swelling, and ideally a slightly padded sole for extra comfort on uneven sand.
Simple gold jewelry: A couple of thin gold chains, small hoop earrings, or a dainty bracelet adds a touch of polish without being overdone. Gold tones warm beautifully against tanned or sun-kissed skin and complement the earthy neutrals of a knit cover up.
Tips for a Comfortable and Safe Beach Day During Pregnancy
Wearing a great outfit is only part of the equation. Actually enjoying a beach day while pregnant requires a little extra planning. Here are some practical tips that have made a real difference on my own beach days this summer.
Hydration is everything. Pregnant women are at higher risk of dehydration, and the heat makes it worse. Bring more water than you think you need. A large insulated water bottle that keeps drinks cold for hours is one of the best investments you can make for summer pregnancy. Add some electrolyte packets if you tend to sweat heavily or are spending several hours in direct sun.
Time your beach visits wisely. The hours between 10am and 2pm are when UV rays are at their strongest. If possible, plan your beach visits for the morning or late afternoon. You get the best light for photos anyway, the sand is less scorching underfoot, and the temperature is more manageable.
Bring shade with you. A pop-up beach tent or large umbrella is worth every penny. Being able to step out of direct sunlight while staying at the beach means you can stay longer, stay cooler, and protect your skin without having to retreat to the car or indoor AC.
Apply sunscreen generously and often. During pregnancy, your skin is more vulnerable to sun damage and melasma (also called the mask of pregnancy), a condition where dark patches appear on the face. Use a broad-spectrum SPF 50 sunscreen, reapply every two hours and after swimming, and pay extra attention to your bump and any skin that might not typically see much sun.
Listen to your body. This sounds obvious but it is worth saying. If you feel overheated, dizzy, or uncomfortable, get out of the sun immediately. Overheating during pregnancy can be dangerous for both you and the baby. Know your limits and do not push them just to extend a beach day.
Bring something comfortable to sit on. A lounger, a thick beach blanket, or even an inflatable pool float in the sand can make a huge difference when sitting on a towel becomes uncomfortable with a belly. Some women find that a pregnancy pillow under the belly or behind the lower back makes beach lounging genuinely comfortable rather than just tolerable.
Where to Find Similar Pieces
I get questions constantly about where to shop for maternity swimwear and cover ups that actually feel stylish, so here is a breakdown of some places worth exploring.
Dedicated maternity brands like HATCH, Storq, and Ingrid & Isabel carry beautifully designed maternity swimwear that is built specifically to accommodate changing bodies. These tend to be higher investment pieces, but the quality and fit are genuinely worth it if you are planning multiple beach trips.
Many mainstream swimwear brands now carry extended sizing or bump-friendly styles that work beautifully for maternity even without being specifically labeled as such. A flowy one-piece or a high-waisted bikini in a size or two up from your pre-pregnancy size can fit perfectly over a bump with the right styling.
Smaller boutiques and Etsy shops have become an incredible resource for handmade knit cover ups and crochet beach pieces that are often more unique and affordable than designer maternity options. Many sellers also offer custom sizing, which is incredibly helpful when standard sizing does not accommodate your particular bump and body shape.
And honestly, do not overlook the resort or swim sections at brands you already love. A lot of non-maternity beach cover ups in relaxed or oversized styles work perfectly during pregnancy — you just have to be willing to try them on and see how they fall over your bump.
Embracing Your Pregnant Body at the Beach
I want to close with something that goes beyond outfit advice, because I think it matters just as much as anything else in this post.
It can feel vulnerable to be at the beach while pregnant. Your body is not the body you are used to. Things fit differently, look different, feel different. You might feel self-conscious about your belly, your fuller hips, your swollen ankles, or the stretch marks beginning to appear. Social media does not always help — the curated images of glowing, perfectly proportioned pregnant bodies can set an unrealistic standard that leaves real women feeling like they do not quite measure up.
But here is the truth: a pregnant body at the beach is a beautiful thing. The bump that makes it harder to find a swimsuit is the same bump that holds a person you are going to love more than anything you have ever loved before. The extra weight you are carrying, the fullness in your face and arms, the way you move more slowly and deliberately — all of it is purposeful. All of it is remarkable.
Dress in ways that make you feel good. Choose fabrics that feel comfortable on your changing skin. Pick colors and patterns that make you smile. Take the photos. Wear the bikini. Go to the beach even on the days when getting there feels like an expedition.
You deserve to feel beautiful this summer, and you already are.
I hope this look gives you some real inspiration for your summer beach days. Whether you are in your first trimester and still feeling somewhat like yourself or in your third and feeling like a magnificent, waddling miracle, a great outfit can genuinely change how you feel stepping onto that sand. The knit cover up and striped shorts bikini combination is one of those effortless looks that requires almost no styling effort while still looking like you tried — which is exactly what pregnancy fashion should be.
Happy summer, mama. You are glowing.
