I just got 3 of these sport bras.  They look good on but the size does run small.  I would suggest ordering a cup larger than you normally wear.  Also the fabric isn't the strongest, so if you are larger chested these would not be a good choice for sports or anything you might need good support doing.  I bought these to wear under tank tops and sleeveless shirts at work, they work fine, and look okay if they show a little through the side of the shirts, but I would NEVER wear them to exercise or run in because of the lack of support.
