Easy and Simple Crochet Bikini Tops and Shorts Patterns

There is something undeniably magical about wearing a handmade swimsuit to the beach. When you slip on a crochet bikini top that you made yourself, stitch by stitch, you carry with you a kind of quiet pride that no store-bought piece can replicate. Crochet swimwear has surged in popularity over the last few years, and it is easy to see why. The open-stitch texture, the boho aesthetic, the ability to customize fit and color — these are things that make crochet bikinis a beloved project for makers of all skill levels.

Whether you are a beginner who just learned to chain or an experienced crocheter looking for your next summer project, this guide will walk you through everything you need to know about easy and simple crochet bikini tops and shorts patterns. From materials to stitch choices, sizing tips to styling ideas, consider this your complete starting point for a wardrobe full of handmade beach looks.

Why Crochet Bikinis Are Worth Making

Before we dive into patterns and techniques, it is worth pausing to appreciate why so many crafters are drawn to crochet swimwear in the first place.

First, there is the cost factor. A high-quality handmade crochet bikini can retail for hundreds of dollars at boutiques and specialty shops. When you make one yourself, you invest a small amount in quality yarn and a few hours of your time. The result is often far more beautiful and personal than anything you could buy off a rack.

Second, crochet swimwear is endlessly customizable. You choose the color, the stitch pattern, the tie length, and the coverage. You can make a top with more support, add extra rows for a longer hem on the shorts, or adjust the strap style to flatter your specific shape. That level of personalization is simply not available in mass-produced swimwear.

Third, crochet is meditative. The rhythmic motion of working through rows of simple stitches is calming, and a bikini project is small enough to feel manageable even on busy days. You can work on it during a lunch break, while watching television in the evening, or on a lazy weekend morning with coffee in hand.

Finally, handmade swimwear sparks conversation. Wear your crochet bikini to the beach and you will almost certainly hear someone ask where you got it. Saying “I made it myself” never gets old.

Choosing the Right Yarn for Crochet Swimwear

Not all yarn is created equal, and this is especially true for swimwear. The yarn you choose will determine how comfortable your finished piece feels, how well it holds up to sun, salt, and chlorine, and how the garment drapes on your body.

Cotton yarn is the most popular choice for crochet bikinis and shorts. It is breathable, absorbs water without becoming uncomfortably heavy, and holds its shape well. Look for a tightly twisted cotton yarn rather than a fluffy one, as this will give your stitches a clean, defined look. Mercerized cotton, which has been treated to add a slight sheen, is particularly lovely for swimwear.

Nylon or polyester-blend yarns are another excellent option. These synthetic fibers dry quickly, resist color fading from sunlight, and tend to have a slight stretch that makes swimwear more forgiving in terms of fit. A cotton-nylon blend often gives you the best of both worlds — the soft feel of cotton with the durability and quick-dry properties of synthetic fiber.

Bamboo yarn is worth mentioning too. It has a naturally silky texture, is eco-friendly, and drapes beautifully. However, it can be slightly heavier when wet, so it works better for cover-ups or shorts than for tops if you plan to swim actively.

For yarn weight, most crochet bikini patterns call for fingering weight (also called size 1 or sock weight) or light DK weight yarn. These finer yarns allow you to achieve the delicate, lacy look that makes crochet swimwear so appealing, and they work up relatively quickly with a smaller hook — typically a size B (2.25mm) to E (3.5mm) crochet hook.

Essential Tools and Supplies

Beyond yarn and a hook, you will need a few other supplies to complete your crochet bikini project successfully.

A tapestry needle is essential for weaving in your ends neatly. Ends that are woven in securely will not unravel during your day at the beach, which is exactly what you want.

Stitch markers help you keep track of pattern repeats and increases or decreases, especially if you are adjusting the pattern to fit your specific measurements.

A measuring tape is your best friend when making fitted garments. Measure frequently as you work to ensure your piece is growing at the correct rate.

Swimwear elastic (sometimes called knicker elastic) is a helpful addition if you want to add extra support or security to the waistband of crochet shorts or the underband of a bikini top. Look for elastic that is labeled as chlorine-resistant so it maintains its stretch over the life of the garment.

If you plan to add removable bra cups or padding, keep in mind that most crochet bikini tops have a loose enough stitch that the cups can be tucked in between the lining and the outer layer, or simply slipped behind the fabric for extra coverage.

Understanding Basic Stitches Used in Bikini Patterns

Most easy crochet bikini patterns rely on a small handful of stitches. If you are comfortable with these, you are well-prepared to tackle almost any beginner-friendly swimwear pattern.

Chain stitch (ch): This is the foundation of most crochet projects. Chains are also used to create the ties on bikini tops and the waistband ties on shorts.

Single crochet (sc): A tight, dense stitch that is perfect for waistbands, edges, and anywhere you want a more structured look. Single crochet does not have much drape, which makes it ideal for straps and ties.

Half double crochet (hdc): A slightly taller stitch with a softer drape than single crochet. Half double crochet is often used for the body of bikini tops, as it creates a fabric that is not too open but still has a lovely texture.

Double crochet (dc): Taller still, and with more drape, double crochet is used widely in lacy stitch patterns and in the body of bikini shorts. It works up quickly, which is a bonus when you are eager to get to the beach.

Shell stitch: A combination stitch where multiple double crochets are worked into the same stitch, creating a fan or shell shape. Shell stitch bikini patterns are timeless and beautiful, and the pattern repeat is simple enough for most beginners to follow after a few rows.

Granny square: Yes, granny squares are not just for blankets. A classic granny square bikini top is one of the most charming and recognizable crochet swimwear styles. Two granny squares connected with ties make an effortlessly bohemian top.

Simple Crochet Bikini Top Patterns

Now let us get into the heart of the guide: the actual patterns. The following descriptions outline popular styles of easy crochet bikini tops, along with general guidance on how to approach each one.

The Triangle Bikini Top

The triangle bikini top is the most classic crochet swimwear style, and for good reason. It is simple, flattering on many body types, and endlessly adaptable.

To make a basic triangle top, you typically begin at the bottom point of the triangle and work upward in increasing rows. Here is a simplified breakdown of the process.

Start by chaining 3 and joining into a ring, or simply chain 3 and work into the first chain. In the first row, work a few double crochets to establish the base. In each subsequent row, increase by working 2 stitches into the first and last stitch of every row. This creates the triangular shape.

Continue working until the triangle is the width you desire for your cup size. A good benchmark is to hold the piece up to your body as you work and stop when the triangle covers the area you want. Most finished triangles are between 6 and 10 inches wide at the top edge.

Once both triangles are complete, work a row of single crochet along all edges to neaten them. Then create long chains (typically 36 to 48 inches) for the neck tie and side ties, attaching them at the appropriate corners. The neck ties attach at the top two corners of each triangle, and the side ties attach at the outer bottom corners. The center bottom corners of both triangles are typically joined together or to a central ring.

The Bandeau Top

A crochet bandeau top is essentially a rectangle worked in the round or flat, with straps or ties added. It provides more coverage than a triangle top and is a great choice for those who want a more secure fit.

To work a simple bandeau, begin by chaining to your desired width (measure the circumference of your bust and chain to that length, adjusting for the natural stretch of your yarn). Join into a round and work in the stitch of your choice — a simple shell stitch pattern creates a beautiful texture — for as many rounds as needed to achieve your desired height. Most bandeaus are between 4 and 8 inches tall.

Add a row of single crochet at the top and bottom edges for a clean finish, then attach ties or straps at the back or work a drawstring channel along the top edge.

The Granny Square Bikini Top

This style consists of two completed granny squares attached with decorative ties. It is arguably the easiest crochet bikini top to make, since the squares themselves require no shaping — just round after round of classic granny square construction.

Make two squares of equal size. The size will depend on your measurements; a 5 to 7 inch square is appropriate for most sizes. Along the top two corners of each square, attach long chain ties for the neck. Along the outer bottom corners, attach ties for the sides. Connect the two squares at their inner bottom corners with a short chain or slip stitch.

The result is a playful, vintage-inspired top that is as fun to wear as it is to make.

Simple Crochet Bikini Shorts Patterns

Crochet shorts are a natural companion to any of the tops above. They double as a stylish beach cover-up and can be worn over a swimsuit bottom for extra coverage and flair.

Basic Crochet Shorts

The simplest crochet shorts are worked flat in two panels (a front and a back) and seamed together at the sides and crotch, with a waistband worked in the round after joining.

Begin by chaining to the width of your hip measurement, then work in double crochet for the desired number of rows to achieve the leg length you want. Most shorts patterns call for somewhere between 8 and 14 inches of length, depending on whether you want a very short style or something closer to a mid-thigh fit.

Shape the crotch by decreasing stitches at the bottom center of each panel over the last several rows, then seam the panels together. Finish by working a waistband in single crochet or ribbing stitch, inserting elastic through a channel if desired.

Crochet Shorts Worked in the Round

For a seamless finish, crochet shorts can be worked in the round from the waistband down. This method is slightly more advanced in terms of construction but produces a beautifully smooth garment.

Chain to your waist measurement and join into a round. Work the body of the shorts in the round in your chosen stitch until you reach the point where the legs split. At that point, divide your work in half and work each leg separately in the round until the desired length is reached.

This method works especially well with shell stitch or a simple mesh pattern, which gives the shorts an airy, beach-ready look.

Shell Stitch Shorts

If you want to make a pair of shorts that looks genuinely impressive with very little effort, shell stitch is your answer. The stitch pattern creates its own texture and visual interest without any complicated shaping.

Work your foundation chain to the desired hip width. In each row, work a pattern of 5 double crochets into one stitch, skip 2 stitches, single crochet into the next stitch, skip 2 stitches, and repeat. This creates a row of beautiful shells. On the return row, work 5 double crochets into the single crochet from the previous row, and a single crochet into the center of each shell from the previous row.

Continue until the desired length is reached, then seam the sides, add a waistband, and finish with a row of single crochet along the leg openings.

Tips for Getting the Perfect Fit

Fit is everything in swimwear, and crochet gives you the rare ability to truly tailor a garment to your body.

Always make a gauge swatch before beginning your project. Crochet gauge can vary significantly from person to person, and working to the correct gauge ensures your finished piece will be the right size. Wet your swatch and let it dry before measuring, as many yarns relax and grow slightly when wet.

Measure yourself carefully before starting. For a bikini top, you need your underbust measurement, your full bust measurement, and the cup depth (the distance from your shoulder to the underbust along the front of your body). For shorts, measure your waist, hips, and the distance from your waist to where you want the shorts to end.

Work increases and decreases gradually rather than all at once. This creates smoother shaping and a more professional-looking finished garment.

Try the piece on frequently as you work, especially if you are making adjustments to an existing pattern. Crochet is forgiving — if something is not fitting correctly, it is usually possible to unravel and rework a few rows without losing much progress.

Caring for Your Crochet Swimwear

Handmade swimwear deserves gentle care. Rinse your crochet bikini in cool, fresh water after each use to remove salt, chlorine, or sunscreen, all of which can break down yarn fibers over time.

Hand wash with a mild detergent and lay flat to dry out of direct sunlight. Avoid wringing or twisting the piece, as this can distort the shape of the stitches. Instead, gently press out excess water with a towel.

Store your crochet swimwear in a cool, dry place away from sharp objects that could snag the fibers.

Styling Your Crochet Swimwear

A crochet bikini top pairs beautifully with high-waisted denim shorts, a flowing linen skirt, or wide-leg trousers for a casual summer outfit that works beyond the beach. Layer it under a sheer kimono or an oversized button-down for a relaxed look that transitions effortlessly from the sand to a beachside restaurant.

Crochet shorts look stunning styled with a simple cropped tank or even a matching crochet top in a complementary color. Add a pair of strappy sandals and a wide-brimmed hat, and you have an effortlessly chic beach look that required nothing more than a hook, some yarn, and a little time.

Final Thoughts

Crochet bikini tops and shorts are among the most rewarding projects a maker can take on. They are small enough to complete in a weekend, practical enough to actually wear, and personal enough to feel truly special. Whether you gravitate toward the simplicity of a granny square top, the classic elegance of a triangle bikini, or the breezy charm of shell stitch shorts, there is a pattern and a style that is perfect for you.

The best part is that once you have made one, you will not want to stop. Each new colorway, each variation in stitch pattern, each small adjustment you make to improve the fit — these are the joys that keep crocheters coming back to the craft season after season. So pick up your hook, choose a yarn in your favorite summer shade, and get started. The beach is waiting.
