I am so genuinely excited to share this Crochet Triangle Bikini Top tutorial with you, because it might be one of my favourite summer makes yet. Each triangle cup is built from a granny square foundation, giving it that airy yet structured texture that feels both nostalgic and completely fresh.
The Triangle Bikini Top
The Crochet Triangle Bikini Top is the kind of handmade piece that makes you want summer to arrive faster. Two triangular cups worked in a granny square style, tied together with long crocheted strings at the back and neck, create a silhouette that feels effortlessly sun-soaked. This top is made for the crafter who wants something wearable, practical, and quietly beautiful. Whether you are brand new to garment crochet or have a few projects behind you, this one is approachable enough to enjoy and refined enough to be proud of.

A dusty rose or mauve, like the one shown here, gives this Crochet Triangle Bikini Top a soft, romantic quality that photographs beautifully against sandy beaches or terracotta walls. But it would be equally lovely in warm terracotta, sage green, butter yellow, or even a crisp off-white for a classic look. Style it over high-waisted linen trousers for a coastal afternoon, or wear it as intended at the beach with matching crochet bottoms.
Materials and Tools
For this Crochet Triangle Bikini Top, you will want to reach for a sport weight or DK weight cotton yarn, which gives the fabric that crisp, clean drape while remaining breathable against the skin on warm days. A 100% cotton or a cotton-blend fiber is strongly recommended, as it holds its shape well when wet and washes beautifully season after season. The hook used in the video tutorial is a 4mm crochet hook, which pairs perfectly with DK cotton to produce a firm but supple fabric. A blunt tapestry needle will also come in handy for weaving in your ends once the cups are complete.
Stitch by Stitch
This pattern draws on a small, satisfying collection of classic crochet stitches that work together to form the granny square triangle base.
BULLET:Magic Ring [The foundation of each cup begins here, pulling the starting loop tight so no hole remains at the centre of your triangle.]
BULLET:CH (Chain) [Used throughout to create spacing between stitch clusters and to build the long tie strings that wrap around the neck and back.]
BULLET:DC (Double Crochet) [The primary building stitch, worked in clusters to form the signature granny square texture across each triangular cup.]
BULLET:SC (Single Crochet) [Worked along the edges of each cup to create a neat, clean border that gives the finished piece a polished, structured outline.]
There is a meditative rhythm to repeating those DC clusters round after round, and once your hands find their pace, the triangle seems to grow almost on its own.
Construction
Each cup of the Crochet Triangle Bikini Top is worked individually in the round, beginning from a magic ring at the tip of the triangle and expanding outward with increasing DC cluster groups in each round to form the granny square shape. Once both triangles are finished and edged with SC, they are connected at the centre with a short crocheted bridge, and long chain tie strings are added to the top and sides. The full step-by-step process is explained clearly in the video tutorial, which walks you through every round with close-up footage so nothing is left to guesswork. If you want to adjust the cup size, simply work one or two additional rounds before finishing the edge, making this an easy pattern to customise for your own fit.
Wearing Your Triangle Bikini Top
Finished and tied, this Crochet Triangle Bikini Top becomes the centrepiece of a slow summer wardrobe. Wear it at the beach or pool with matching crochet bottoms, layer it under a sheer linen kimono for a bohemian afternoon look, or tuck the strings into high-waisted denim shorts for a casual summer top that turns heads at the market. The closer you get to finishing those last few rounds, the more you will feel the pull of sun, salt, and somewhere warm.
Washing and Caring for Your Crochet Triangle Bikini Top
Because this top is made to be worn near water, a little care goes a long way in keeping it looking its best season after season. Hand washing in cool water with a gentle soap is the kindest method, and rinsing thoroughly before laying it flat to dry will help the cotton fibers keep their shape and colour. Avoid wringing or twisting the fabric, as this can distort those beautifully formed DC clusters over time. When storing between seasons, fold it loosely and keep it away from direct sunlight to prevent any fading of that gorgeous dusty rose hue.
Making something you will actually wear with your own hands is one of the most quietly radical acts of the slow-fashion movement, and this Crochet Triangle Bikini Top is a beautiful place to begin or continue that practice.
