    The Perfect Racerback

    Worth waiting for the restock on this bra. Perfect styling for my tank tops and other sleeveless clothing.

    Great bra

    Very comfortable and great with racerback tanks. I do wish there was a tiny bit more coverage on top of breasts.

    Almost…

    Ordered this for my wife. She indicated that she loved the color and for the most part the fit. Indicated that with her body frame these types of bras do not fit her well. While we returned this to get something she’ll wear more often she had nothing but good feedback otherwise.

    Good except for the clasp

    The mesh is cool and the support is comfortable and good. I struggle with the front clasp a little and worry it will break plus it is a little itchy. Otherwise well designed.
