This crochet pattern is for a unisex design, with an open string front and back, up to a choker style neck. Designed using a male mannequin and to male standard sizes, I expect it will be attractive to all people.
Sizing was nearly impossible with the amount of stretch in the crochet. Measurements around the body apply to the hem and the chest. Length sizes go from shoulder seam to hem.
I have used DK Cotton to make this shirt, specifically Paintbox Yarns Cotton DK
