I feel so elegant and put together in it. Bonus, it stays put for trying out new sports on boards... like wing surfing! I usually wear a size small in most outdoor activewear, but based on the reviews and models measurements I decided to go with M. It was a good choice, but the small may have also worked! I am 5'5" 125lbs, 34 bust, 28 waist, 37 hips.
