    too small!

    Pretty, but, unfortunately, it is small. I contacted them about it and it seemed they encouraged giving it a try I should have returned it.

    The white was too visible under clothes

    I love the fit and style of the sieve triangle bra, but the white trim was too visible under all my white tanks and t-shirts for summer, so it was returned.

    Great fit and look!

    I have worn this bra a couple times now. It is very flattering and I enjoy to wear it. It is comfortable when sitting and being active (walking long distances.) The band does not roll or dig in. The navy color still somewhat disguises the nipples. I am a 34C and a size 2 fits great.

    A Subtle Sexy

    This bra is surprisingly supportive and has this super subtle sexy vibe.

    It runs a little small in the band, so I'm exchanging it for a size up. It is super comfortable as is, but is squeezing in the back a little more than I'd like
