Crochet Bikini Ideas: Step-by-Step Guide for Beginners


Crochet bikinis have become a trendy and stylish choice for beachwear, combining the classic craft of crochet with modern fashion.

Creating your own crochet bikini allows you to customize the fit, color, and design to your liking.


Whether you’re a beginner or looking to expand your crochet skills, this guide will walk you through the process of making a simple yet chic crochet bikini.

We’ll explore ideas for different styles and provide step-by-step instructions to get you started.

Materials Needed

Before starting your project, gather the following materials:

  • Yarn: Use a lightweight, stretchy yarn suitable for swimwear, such as cotton-blend or microfiber yarn. You’ll need about 300-500 yards, depending on the size and style.
  • Crochet Hook: A size G/6 (4.0 mm) or H/8 (5.0 mm) hook is recommended, but check your yarn’s label for the best hook size.
  • Stitch Markers: To mark important points in your project.
  • Tapestry Needle: For weaving in ends and seaming.
  • Scissors: For cutting yarn.
  • Lining Fabric (Optional): For added comfort and coverage.

Gauge and Sizing

Gauge is important for swimwear to ensure a snug fit. For this project, a 4×4 inch (10×10 cm) square should equal 16 stitches and 20 rows in single crochet (SC). Make a swatch to check your gauge and adjust your hook size if necessary.

Bikini Top Styles

There are several styles of crochet bikini tops to choose from, but we’ll focus on two beginner-friendly designs: the triangle top and the bandeau top.

Triangle Bikini Top

The triangle bikini top is a classic and flattering style. Here’s how to make it:

  1. Foundation Chain: Start by chaining 14 (or adjust based on your desired cup size).
  2. Row 1: SC in the 2nd chain from the hook and in each chain across. (13 SC)
  3. Row 2: Chain 1, turn your work, SC in each stitch across. When you reach the last stitch, make 3 SC in that stitch to create the point of the triangle. Continue SC down the other side of the chain, making 1 SC in each stitch. (27 SC)
  4. Row 3: Chain 1, turn, SC in each stitch up to the point. In the center stitch (the point), make 3 SC. SC in each stitch down the other side. (29 SC)
  5. Rows 4-10 (or until desired size): Repeat Row 3, increasing by 2 stitches on each side with each row. Adjust the number of rows for more coverage.
  6. Edging and Straps:
    • SC evenly around the entire cup.
    • For the straps, chain 50 (or more for longer ties) at each corner of the cup. Attach them to the top of the triangle and at the sides for secure ties around the neck and back.
  7. Repeat for the second cup.

Bandeau Bikini Top

The bandeau top is a simple tube style that can be dressed up with additional details like ties or ruffles.

  1. Foundation Chain: Chain 80 (or adjust based on your bust measurement).
  2. Row 1: SC in the 2nd chain from the hook and in each chain across. Turn your work. (79 SC)
  3. Rows 2-10 (or desired width): Chain 1, SC in each stitch across. Turn your work.
  4. Seam: Fold the piece in half lengthwise and seam the short ends together using a tapestry needle or slip stitch to form a tube.
  5. Edging and Straps:
    • SC evenly around the top and bottom edges for a clean finish.
    • For optional straps, attach yarn at the top corners and chain 50 (or desired length) for ties around the neck.

Bikini Bottom Styles

For the bottoms, we’ll cover a basic bikini bottom and a high-waisted option.

Basic Bikini Bottom

  2. Row 1: SC in the 2nd chain from the hook and in each chain across. Turn your work. (15 SC)
  3. Rows 2-10: Chain 1, SC in each stitch across. Turn your work. Adjust the number of rows for the desired length of the crotch area.

  7. Seam the Sides: Align the front and back panels and seam the sides together.

Finishing Touches

  1. Lining (Optional): If you prefer extra coverage, sew a soft lining fabric to the inside of the bikini top and bottoms.
  2. Weave in Ends: Use the tapestry needle to weave in any loose ends from your seaming and finishing.
  3. Blocking: Gently block your pieces to even out the stitches and shape the bikini.

Tips for Success

  • Customize Your Fit: Adjust the foundation chain and the number of rows to tailor the bikini to your body measurements.
  • Experiment with Patterns: Use different stitch patterns like shell stitches or granny squares for unique designs.
  • Color Play: Mix and match colors to create stripes, ombre effects, or color blocks.
  • Check Fit as You Go: Try on the pieces during the assembly process to ensure a comfortable fit.
