I plan to print a small quantity of items on various tees from the clothing store, Forever 21. Before I begin I would like to make sure I'm not doing anything illegal by printing on their tees. Also, I would like to make sure I avoid doing anything illegal when/if using the tees. I don't plan to remove the labels or mandatory tags. I'm not 100% if they will be sold yet. Back to the original question, is it okay to print on tees from clothing stores?
