Like most of the other reviews here, the shirt runs too small and too short. Material was also incredibly uncomfortable. It also wasn't the color I was hoping it would be, but that's on me for not reading the fine print (eggshell white was very much not white) If you're looking at this for a certain costume/cosplay idea, it's probably not what you're looking for.
