Runs big. Shirt and pants are two different shades of red

I'm 4'11, 145 pounds, and these fit PERFECT on me in a medium. It was only a teeny tiny bit tight pulling them over the butt. But other than that these are amazing. They look identical to the picture, nice deep reds and good graphics. They are also the perfect length, they don't bunch up at the ankles which is hard to find.
