I should have ordered a medium size, but after reading the reviews about them running big, and also looking at the size chart, I decided to order the small. I should have gone with my instinct and ordered Medium. I just had to return them to exchange. Too small, and did not fit. I am 5'9" and 170 # and both the pants and top were too small. The color and fabric seemed fine, but size was an issue. If you are normally a med, then get medium. Don't go too small.
