Our best selling bra for a reason.


The most supportive of our wireless bras. Great shape, naturally smoothing, airy light and sexy sheer — Belgian micromesh might just be magic.

    Simple and elegant

    This is a great alternative to a bralette-more shape and elegant material. Not a bra to sweat in though!

    Great fit and overall bra

    Great bra and comfortable! The fabric is perfect for summer, I just wish the sizing were more nuanced.

    So Good!

    I have tried several other non wire bras over the years and nothing even came close to the Sieve Non Wire Bra. I can actually wear it for every day. Support and comfort are excellent.
