With just a few supplies and a bit of time, you’ll be wearing your handmade Easy Crochet Triangle Bikini in no time. Let’s dive into this fun summer pattern and start stitching!
When starting your Easy Crochet Triangle Bikini, selecting the right materials is crucial to ensure comfort, durability, and fit. Cotton-blend yarns with a bit of stretch, like a 100% mercerized cotton or a bamboo-cotton mix, are ideal because they provide breathability and hold their shape well, even when wet.
Make sure to choose a yarn that is labeled as sport weight (category 2 or 3) for a lightweight feel that isn’t too bulky. You’ll need approximately 150–200 yards of yarn for the bikini top and an additional 200–250 yards for the bottoms, depending on your size.
Use a 3.5mm (E) crochet hook for tight, durable stitches. A smaller hook helps prevent the bikini from becoming too loose when worn. Also, have a tapestry needle handy for weaving in ends and a measuring tape for accurate sizing.
Before you begin, take body measurements including bust width, cup height, and hip circumference. This will ensure your Easy Crochet Triangle Bikini fits just right. A well-fitted bikini not only feels better but also looks more polished and professional.
If you’re a beginner, this project is a great way to practice simple stitches like single crochet (sc), double crochet (dc), and slip stitch (sl st). These basic stitches are the foundation of the pattern and are easy to learn with just a little practice.
Lastly, prepare a flat workspace and gather all your materials before starting. A clutter-free environment will help you stay organized and make the process of crocheting your Easy Crochet Triangle Bikini much smoother and more enjoyable.
Creating the bikini top begins with making two triangular cups. Each cup is crocheted individually and then joined with a band under the bust and ties for neck and back support. Follow this easy pattern to create your perfect fit.
Foundation Chain: Start by chaining 13. This will be the base of one triangle cup. You can adjust the number of starting chains based on your cup size.
Row 1: Begin in the second chain from hook. Work 1 single crochet (sc) in each stitch across. (12 sc). Chain 1 and turn.
Rows 2–12: Decrease one stitch on each side every second row to create the triangle shape. Continue single crocheting in the center stitches, leaving one unworked on each end every other row. You should end with a point.
Cup Edging: Once the triangle is shaped, single crochet around the entire cup to create a clean edge. Make 3 sc in the top point to form a loop for the neck tie.
Repeat: Make a second identical triangle following the same steps. Ensure both triangles are symmetrical in size and shape for a balanced fit.
Join and Add Ties: Chain a band of 60–70 stitches (or more for larger sizes) to join both cups. Attach the chain to the bottom of the cups using slip stitches. For neck and back ties, chain 70 stitches each and secure them to the top of each cup and the band ends.
Once the top is complete, the next step is crocheting the matching bikini bottoms. The process is just as beginner-friendly and can be customized for different levels of coverage. Let’s make a pair that complements your Easy Crochet Triangle Bikini top.
Foundation Chain: Chain 18–22 for the crotch area (adjust based on your hip size). Work 1 sc in each chain for the first row.
Increasing Rows: To shape the front panel, increase 1 stitch on each side every second row for the next 8–10 rows. This creates the gentle widening needed for the front.
Middle Section: Continue with the same number of stitches for about 8 rows without increasing to form the widest part of the bikini front. This area should comfortably cover your lower stomach area.
Back Panel Shaping: Begin decreasing 1 stitch on each side every second row for 8–10 rows until you return to the same number of stitches as the foundation chain. This creates the classic tapered back shape.
Side Ties: To complete the bottoms, add side ties by chaining 60–70 stitches on each end of the waistline. These ties allow for easy adjustments and a perfect fit.
Finishing Touches: Single crochet around the edges of the entire piece for a smooth finish. Make sure all ties are secure and even on both sides. Use a tapestry needle to weave in all yarn ends neatly.
Although you won’t be using traditional fabric, accurate yarn measurements and stitch counts are key to crafting a professional-looking Easy Crochet Triangle Bikini. Let’s break down the approximate sizes and adjustments based on general sizes.
Triangle Cup (Small Size): Each triangle cup should measure approximately 5 inches wide at the base and 5.5 inches tall. Increase both measurements by 0.5–1 inch for medium and large sizes.
Underbust Band: A standard band for the bikini top should be about 26–30 inches long. This includes 2–3 inches of extra length for stretch and tying space. Adjust the chain count based on your measurements.
Back and Neck Ties: For a secure fit, each tie should be at least 16 inches long. Longer ties (20–24 inches) can be left for style variations or decorative bows.
Bikini Bottom Width: The narrowest part (crotch) should be around 2.5–3 inches wide. The widest part (hip area) should measure approximately 6.5–8 inches. Adjust based on personal comfort and size.
Side Ties for Bottoms: Just like the top, the side ties for the bikini bottom should be about 16–20 inches on each side. This makes them easy to knot and adjust.
Yarn Yardage: Total yarn required for a full set (top and bottom) is between 350 and 450 yards depending on size. It’s always better to have a little extra to accommodate variations.
One of the best parts about making an Easy Crochet Triangle Bikini is the ability to personalize it. From color choices to stitch variations, you can tailor it to your taste and body.
Experiment with different yarn colors. Bright neons, soft pastels, or classic neutrals can all create unique looks. Consider adding stripes or color blocking for a trendy, fashion-forward vibe.
Add decorative touches such as small shell beads, tassels, or fringe at the ends of the ties for a boho-chic finish. These little extras give your bikini a boutique feel.
Want more coverage or support? Try adding an extra row or two at the base of the cups or using a thicker yarn for a more substantial result. Lining the cups with fabric is also an option for modesty and support.
If you plan to swim in your bikini, test your yarn in water first. Some yarns stretch or fade when wet. Pre-washing your finished bikini by hand in cold water can help set the shape and prevent shrinkage.
Always let your bikini air dry flat to preserve its form. Avoid wringing it out or putting it in a dryer. Handwashing is best to maintain its integrity over time.
Store your crochet bikini flat or rolled in a drawer rather than hanging, to prevent it from stretching. With the right care, your handmade Easy Crochet Triangle Bikini can last for many summers.

Should I line the bikini?
Optional. Lining adds support and modesty, especially for larger sizes or if the yarn is loosely woven.

Yes, but always credit the pattern source and check for any copyright terms if you’re using a commercial design.
