I purchased this at Nordstrom with help from the lingerie consultant (although sizing is same as normal bra). After about 20 years of leading name (Nike, Champion, etc.) uniboob sportsbras I committed myself to something with more support and better shape. I am small-framed 34DD  and this bra has provided the best support I've ever had in a sports bra, from yoga to running (zero booby bounce, no uniboob). Straps and back band are wide but they both have about 5 options for tightening - I wish all regular bras had shoulder strap tightening like this one. I wash it in a mesh bag in my regular cold cycle and line dry, and 3 years later it's still in great condition. The underwire is on the outside, which I think is genius, as it never cuts into the skin yet you can never see it under even a tight t-shirt or tank. Minimal stretching at straps and band. My only negative is that since it's full coverage, the fabric at top of the cups come up pretty high an peaks above my Underarmour workout tanktops, but it's a small price to pay for such a great bra. Definitely highly recommended for larger busts who need good support for moderate-to-heavy activity, but I think smaller chests (smaller than a large C cup) could get away with something less.
