I have not added anything to the sweatshirt yet, because I wasnt sure how well this company does with sizing so I sized up and they are too big. That's my fault. I've read other peoples reviews and said they had no problem with exchanges, but when I tried to start a return, it looked like I'd have to pay for shipping so I haven't done it yet. They look thick and good shape. If you get the right size you'll probably be happy.
