    Square Neck One Piece | Black
    Rated 4 out of 5 stars
    Love the fabric

    I was really hesitant on purchasing any of the swim. I'm a 40 G cup size and while I LOVE the fabric, it's sliming and will have you snatched, it just isn't big bust friendly. I'm glad I was able to grab it on discount and will definitely wear it. Just wish it had more boob support.

    Gorgeous color

    I was really hesitant on purchasing any of the swim. I'm a 40 H cup size and while I LOVE the fabric and color, it just isn't big bust friendly. I'm glad I was able to grab it on discount and will definitely wear it. Just wish it had more boob support.

    Square Neck One Piece | Coffee
    Rated 5 out of 5 stars
    So flattering

    I never thought I’d like a one piece without full booty coverage but this surprisingly looks so good. I still haven’t got back to where I want to be since I’m still breastfeeding, but this suit makes me feel more confident. Mine did come with a small snag, but customer service was more than helpful! You will not be disappointed in this swimming suit.
