Surprisingly supportive. Balconette cut.


Brought back an old favorite. This bra is the best of all words: supportive, sexy, functional, flattering.

    Beautiful, runs too small

    This bra is so lovely, the design and fabric are perfect. However, though the Sieve Demi Bra in 34DD has been my go to for years now with a perfect fit, this style does not fit me. I'm so sad to return it since there isn't an option for a bigger cup size in this style. Please make bigger cup sizes!! Or have the sizing be more consistent with other styles.
