What You’ll Need

• Yarn: Worsted (Weight 4) 100% Cotton yarn — approximately 150 yards total. (Cotton is highly recommended as it holds its shape when wet and breathes well in the heat.)
• Hook: US G/6 (4.0 mm) crochet hook
• Notions: Yarn needle, scissors, measuring tape
• Gauge: 16 sts × 18 rows = 4″ in single crochet

Tips Before You Start

1. Gauge check: While a bikini top is small, gauge is critical for garments! A tighter gauge ensures the fabric is dense enough to be nonsee-through.
2. Yarn substitution: If you can’t find 100% cotton, a cotton-bamboo or cotton-acrylic blend will work, but avoid 100% acrylic or wool for swimwear, as they can sag or feel too warm.
3. Customization: Need a larger or smaller cup? Simply add or subtract starting chains in multiples of 2. To make the cup taller without making it wider, add more even rows between your decrease rows.

Pattern Instructions

Special Stitches

sc2tog (single crochet 2 together): Insert your hook into the next stitch, yarn over, and pull up a loop (you now have 2 loops on your hook). Insert your hook into the next stitch, yarn over, and pull up another loop (you now have 3 loops on your hook). Yarn over and pull through all 3 loops on your hook (you have decreased the stitch count by 1).

Notes

• Pattern is worked flat in rows from the bottom up to form a triangle.
• Ch 1 at the beginning of rows does NOT count as a stitch.
• Stitch counts are given in bold at the end of each row.

• Color block: Crochet the edging and straps in a contrasting color for a fun, sporty look!
