Ok someone on DA asked for reference but thought I share on here too - why not.
His undershirt I realize will be a bit tricky. The sleeve is all ONE but you can be creative with it. Ideally the cuff at the top connects the sleeve to the glove part, but doesn’t have to, you can figure out something easier if you can :3
Again, if you need more ref or ref sheet for another design I will help you!!
