the top of the cup really almost fit, one of my boob is slightly bigger of the other and the quadboob effet was almost starting ; when looking from the side it was visible ; when streching my arms, jumping a bit or moving fast, it apperead fot both boobs and there was too much giggling at the top of the cup for it to be perfectly comfortable and a perfect fit. The top of the cup simply was not covering enough in its form and it didn't matched with my breast shape. Otherwise the cup offers great support.
