Crochet Pattern Bikini Top – This is a crochet pattern for just the bikini top in both English and US terms. The recommended directions for general sizes XS, S, M, L, and XL (bra cup sizes from A to DD) are included in the design. Additionally, you may see references for various body shapes in the testers’ remarks and a guide to customize it to your unique fit.
Written directions, illustrations, a stitch count for each size at the end of each row, and an extra note to help with comprehension are all included in this design.
For this project, I chose yarn that is 100% cotton; as the top fits close to the body, I recommend using yarn that has a nice touch.

Bikini Top – Edging and Straps
Row 1: From the corner of the last ST for the normal row (see diagram ① ↓)1SC into each ST across to the end. After the last SC, continue to CH up 80 (90, 100, 110, 120) or any length preferable for the neck strap.
Row 2: SL ST in the back hump of each CH ST all the way back. SC in the side of the SC row. 1SC into each of the SCH rows. CH1, cut the yarn and fasten off.

Row 1: Reattach the yarn with a SL ST in the first SC we made for the edging (see diagram ↑ ②) and continue to CH up 90 (100, 115, 125, 140) or any length preferable for the back strap.
Row 2: SL ST in the back hump of each CH ST all the way back. 1SC into the side of the SC row. 1SC into each of the SCH rows. CH1, cut the yarn and fasten off.
*REP above steps to make the second bra cup.
*Remember to start the SC on the ring from the wrong side so that the Herringbone ST would appear on the same side of the cups.
*For the second bra cup, do the back strap first and the neck strap after so the two cups are symmetric.
Weave in all the yarn ends and we are done.
