This crochet pattern is for a men’s shirt, with a textured diagonal stitch. You can choose to have a dramatic arrow shaped stripe across the back or keep it plain and simple. The design is loose fitting and I considered it appropriate as beach wear or casual wear as the crochet does create a mesh effect.
I have used DK Cotton to make this shirt, specifically Paintbox Yarns Cotton DK
