Hey! With clothes, sizing depends a lot on what you are accustomed to. Our guys tees run a little bit smaller than a traditional boxy tee, but true to size for most mall retail outlets. Our girls tees run small... just a little bit bigger than juniors sizing. Both men's and women's are 100% pre-shrunk soft ring spun cotton. While they are pre-shrunk, they will still still shrink a bit more in the dryer. This happens with all 100% cotton clothes, and can be minimized by drying with low heat. Our limited edition tri blend prints ( available on Thursdays) will not shrink, as they are polyester, rayon, and cotton. Does that help!? If you have more questions about it, please email us at orders@snorgtees.com. Sarah can give you measurements on the shirts. Thanks!
