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.

    size is not consistent

    I have many of your Sieve bras but this last one and one earlier are significantly smaller than all the other size 2s. I wish I could confidently order size 2 and have it fit like the others.

    My perfect bra

    Light, airy fabric with good support and zero underwire. Looks great on, is comfortable & no band roll. As reference: I’m a 34DD/5’1”/125lb and bought the 2+. It’s a perfect fit me me!!
