I am still doing Free to use shirts. Well I say do I just have them left over designs. So For this a cutie mark is optinal. What you do is if your OC has a cutie mark you rub out the Cute mark here and put the your cutie mark there.

This is optional since not all OC have a cutie mark, don't want a cutie mark or lost it my some other means?

This can be any couller tshirt
