    Sizing way off

    The XL bra measures 29 inches at the band and 34 inches at the bust. Even allowing for stretch for shaping and support, this makes no sense. I could not even get it on.

    Best Sports Bra I've Ever Owned

    Absolutely love this sports bra. Their bras really do mold to your body, so it's super comfortable, supportive and fashionable! For my hot HIIT class - I just wear it on its own.

    Pretty Bra

    This bra is pretty for a sports bra! The top and bottom ends of the side seams could be finished smoother as they do rub the skin somewhat. The fabric does not wick moisture as well as sports bras from other brands.
