    Effortlessly beautiful and functional

    My daily staple. I am 5’6” 133# 36A-B. I wear a 2. The wide band though snug initially ultimately forms comfortably to your body so that you forget you’re wearing a bra until it’s time to take it off. Form and function at its finest.

    the cutest bra

    I'm in love. If only Negative made a panty that is not a thong in a matching color.

    Supportive and comfy

    The triangle style of sieve bra is my favorite one - the fit is perfect and it has just enough support.
