88% Polyester+12% spandex athletic fabric. Feels like a nice quality blend of polyester blend used in our shirt and it hasn't irritated your dears skin or anything. Machine wash or even violent mixed machine wash is allowed because it will not fade and change line. The smooth cloth shirt is no ironing needed. Don't prepare in advance. Just put it on when you need it or go out. Tie dye clothing has been a beloved fashion statement for decades, and it doesn’t look like it will be going out of style anytime soon. If your kids have not already asked for a tie-dyed T-shirt, it is likely that they will request one once they see their friends wearing them. Although tie-dyed clothes can be made at home, the project can be extremely messy, so purchasing a pre-made shirt is appealing to many parents.
