I bought two of these for my kids and found them to be true to size. I have washed and dried them and, do far, they have kept their size and shape. It is getting harder to find basic LS all cotton t-shirts and most inexpensive ones have cuffs at the bottom of the sleeves but not these shirts so they fit nicely and are comfortable (so my kids claim - and they usually let me know if things aren't comfortable!). Overall very pleased with this purchase!
