I work in a professional setting, and when I get home in the afternoon, the first thing I do is change into my "play clothes": my Ibex wool pants an shelf bra top and sweater.... Since I have gotten the balance sport top, it is the only undershirt I want to wear....it is supportive enough to go to the bouncy house place, just the right amount of stretch. The color is gorgeous (burnt rose). I do have the open the straps all the way to prevent them digging in. I normally wear a small in other brands, but the medium in this is perfect. Thank you Ibex!
