While the pattern may only list S - XL for sizing I have plenty of notes to help adjust for the more busty customers! This pattern is designed to be fitted with a strappy open back and a tie at the neck with an optional Halter neck alternative. This pattern is completely customizable so feel free to improvise and adjust! Use a longer chain for wider chests and more rounds for a bigger cup. Keep in mind the back straps are also completely adjustable. The sizes below are in US sizing.

Materials Needed include -
Yarn: 24/7 cotton (4 weight) 100% cotton (or cotton blends - cotton/polyester is great for bathing suits!)
Crochet hook: size E (3.5mm)
Scissors & yarn needle to weave in ends
