    This is the perfect bra if you are looking for superior support, soft stretch, breathability, and a smooth natural look under shirts. My favorite go to bra!

    My favorite bra

    I only wear HW these days and this style is my favorite. The unlined underwire gives me a great natural shape as a 36B, and is comfy for all-day wear. More fun, bright colors, please!

    My favorite unlined bra

    I love this bra so much. It's so comfortable yet supportive. I love the side slings - one of the things that bother me about a lot of unlined bras is that there's no lift, but the inner side slings give that lift. I like that you can also connect the straps in the back.

    I forget I’m wearing a bra

    I’m a 34D and this has become my favorite supportive bra. Sometimes I leave the house and think I forgot to put a bra on. It’s so soft and comfortable!

    Great everyday bra

    Comfortable, solid bra. Fits 3 weeks out of each month ;) Soft alternative to formed cup bras.
