i thought it fit slightly smaller than other shirts in my closet. i could have ordered a size up and felt better about if it shrinks on me. i did wash it once already and the fit is picture perfect, but i can feel the arms hugging my bicep more than i want. i can't stand clingy tees though. i wouldn't say order up unless you prefer a roomier fit. i tend to wear tees for a few years so i want them to not shrink too much if they are washed more than 20 times.
