I ordered a medium in the blue. I love the product, the blue is still nice and a relaxed fit, but I prefer my clothes loose so I probably should have stuck with the the large. I still plan to wear the blue medium though, so definitely no complaints. Sizes for me are a pain because I fall right in middle of medium and large, so depending on what fit in want, I go for that size. I'm 5'4" and about 158 if that helps any.
