Sunny days are a great excuse to crochet something fun you can actually wear, and these eight crochet bathing suit ideas give you a nice mix of beginner-friendly tops, fuller two-piece sets, and one-piece looks. I picked direct tutorial pages from different sites so you are not clicking around the same blog over and over. Most of these patterns use cotton or swim-friendly blends, and several include video help too. For the best fit, treat these as made-to-measure projects, check your gauge, and add lining or elastic where the tutorial recommends it. Tutorial choices and pattern details come from the linked sources below.
Crochet Summer Vibes Bikini Top
This crochet bikini top is a sweet beginner option if you want a classic triangle shape with a soft, feminine finish. The tutorial uses cotton yarn, a 3.50 mm hook, and simple stitches like hdc, sc, and dc, so it is approachable even if this is your first wearable. The sample shown on the page is a rich purple shade, which gives it a bold beachy look without needing fancy stitch work. Start by making one cup and checking coverage before the second cup so your sizing feels right from the beginning. The free written instructions and video are in the Summer Vibes Bikini Top Tutorial.

Why it’s great: A simple crochet bikini top that is easy to size as you go and quick to finish.
Crochet Comfy Bralette Bathing Suit Top
If you prefer a little more everyday comfort, this crochet bralette style is a smart pick because it is designed as a beach-ready top and can pair with matching bottoms. The roundup description notes that it is beginner-friendly, adjustable as you work, and made so the ties are added seamlessly to reduce extra finishing. That makes it a practical choice if you dislike sewing lots of ends later. Because it is a bralette silhouette, it also doubles nicely as a festival or layering top outside the pool. Use the linked tutorial to shape the fit to your bust before finishing the bands. Tutorial.

Crochet Sassy Summer Bikini Set
This crochet bikini set is a fuller two-piece idea for anyone wanting both top and bottom from one tutorial. The designer describes it as a full-coverage suit that can be made to fit any size, and the materials list includes Willow Yarns Ripples in the color Friendship, plus a small hook, lining fabric, thread, and sewing needles. That combination tells you right away this pattern is built with better structure in mind than a casual festival top. A good tip here is to finish one test cup first, then compare it against a favorite swimsuit before you commit to the full set. The Sassy Summer Bikini Tutorial includes video help too.

Crochet Classic Triangle Bikini Top
This crochet triangle bikini top is a great choice if you want a clean, timeless shape that still feels handmade. The pattern page says it uses simple stitches, cotton yarn, and includes five sizes from XS to XL, plus guidance to customize further. The photo guide also shows finishing details like beaded straps and fringe added with pink cotton yarn, so it is a nice option if you want a little extra personality without changing the base construction. A helpful tip is to make the plain version first, then add fringe only after trying it on. The Classic Triangle Bikini Top Tutorial is linked below.

Crochet Patons Bikini Set
This crochet bikini set is a strong pick for crocheters who want a straightforward branded pattern with clear measurements. The pattern page says the top fits cup sizes A, B, or C, while the bottom is one size, and it specifically recommends invisible elastic thread for the bottom. It also lists Patons Grace in the color Lotus and gives care guidance including machine wash in cool water and dry flat, which is useful if you want something practical to maintain. My tip here is to insert elastic exactly where the pattern suggests rather than skipping it, because that step helps the fit stay more secure. Tutorial.

Crochet Laia Multi Bikini Set
This crochet bikini set adds a more romantic look thanks to the shell-stitch border details described in the roundup. It is presented as a classic set with a softer finish, and the source notes that it works up quickly and lets you choose your preferred cotton color. That is handy if you want something a bit dressier than a plain triangle bikini. Since shell edging can shift the look quite a lot, block the finished pieces lightly before adding ties so the scallops sit evenly. The direct Laia Multi Bikini Set page is the one to use for the pattern. Tutorial.

Supplies:
- cotton yarn
- hook size listed in tutorial

- scissors
- optional swimsuit lining
Why it’s great: It gives a softer, more decorative crochet bathing suit look without getting overly complicated.
Crochet Rainbow Bikini Top
This crochet bikini top is the cheerful option in the list and perfect if you want a colorful summer make. The pattern page spells out the yarn shades in order: red, red-orange, orange, yellow, lime green, teal, turquoise, red purple, and dark purple, with dark purple used for the border. That makes it easy to recreate the same bright striped effect from the tutorial photos. Because there are many color changes, I would carry yarn neatly or weave ends as you go instead of leaving them all for the end. The Rainbow Crochet Bikini Top Tutorial includes beginner-oriented guidance and video support.
Hashtags: #rainbowcrochet #crochetbikinitop #colorfulcrochet #summerfashiondiy
Supplies:
- cotton yarn in 9 rainbow shades
- hook size listed in tutorial

Why it’s great: A bright crochet bathing suit top that makes the colorwork the star without needing advanced shaping.
Crochet Tropic Twist Swimsuit
For a one-piece option, this crochet swimsuit brings a more statement look than the separate tops and sets above. The tutorial snippet says it is crocheted with special bikini yarn for fit, comfort, and durability, which is exactly the kind of material note you want for a one-piece silhouette. This is a good project when you want a handmade suit that feels more fashion-forward and less like a simple beach bralette. A practical tip is to measure torso length carefully before final assembly, because one-piece swimwear fit depends on vertical length as much as bust or hip size. See the Tropic Twist Crochet Swimsuit Pattern Tutorial.

Supplies:
- special bikini yarn
- hook size listed in tutorial
- yarn needle

Conclusion
A crochet bathing suit can be as simple as one easy top or as bold as a full one-piece statement project. Pick the design that matches your skill level, use the right yarn, and fit-check early so the finish feels comfortable and secure. Save your favorite now, then come back when you are ready to start stitching for summer.
FAQs
What yarn works best for crochet bathing suit projects?
Cotton and swim-friendly blends are the most common choices in these tutorials because they are breathable and widely used for summer wear. Some patterns also call for specialty bikini yarn or elastic support for better hold.
Can I machine wash a crochet bathing suit?
Some can be machine washed, but always follow the specific pattern yarn guidance. For example, the Patons bikini page says cool machine wash and dry flat. When unsure, hand wash and lay flat is the safer choice.
How do I scale a bikini top to fit better?
Choose made-to-measure styles or adjust the starting chain and number of rows in the cups. Several tutorials here explicitly explain size customization while you work.
Are crochet bathing suits safe for real swimming?
They can be made for beach and pool wear, but fit, lining, elastic, and yarn choice matter a lot. Patterns that mention lining, elastic, or specialty bikini yarn are better starting points for a more secure result.
How can I make edges and joins more durable?
Use the border and finishing steps the designer gives, weave ends in firmly, and add lining or elastic where recommended. For colorwork or shell edges, blocking lightly before the final ties can also help.
How much time and yarn does a crochet bathing suit usually take?
Simple tops can be quick afternoon projects, while full sets and one-pieces take longer because of shaping, finishing, and possible lining. Yarn amounts vary by size and coverage, so check the linked pattern before buying supplies.
Why does my crochet bikini curl, stretch, or wave?
That usually comes from tension, yarn choice, or too much looseness in the fabric. Swatching first, using a slightly smaller hook for firmer stitches, and adding elastic or lining where needed can help a lot.
How should I photograph a finished crochet bathing suit for Pinterest or socials?
Use bright natural light, a simple beachy background, and close framing that shows the stitch texture and shape clearly. Flat lays on sand, white towels, or light wood work especially well for colorful tops and sets.
