Designers on Etsy make custom t-shirts to commemorate important events or personalize a gift. Planning your buddy’s bachelor party in Vegas? Work with an artist to create custom men's long sleeve graphic tees for the whole crew. For your little brother’s birthday, get him a shirt with an embarrassing childhood photo plastered on the front. Or, deck out every member of the clan with the family crest displayed proudly on their chests at the next reunion.
