      In a world of push-ups and pink, Negative goes back to basics with a focus on essentials - no itchy lace, no pesky bows."

      This bra is both comfortable and sexy - it's nice to see attention paid to a soft, supportive underband (the root of a bra, after all).

      Love it

      This bra is sooo lightweight, supportive, gives a great shape to my boobs, and actually had pretty great nipple coverage! I am a 34DD and have never experienced this with other bras, even lightly lined ones. After wearing the Sieve bra I realized that my old bras were adding weight and bulk to my already large chest. The Seive actually makes me feel sleek and perky! What! I am sold. I will be coming back for an additional one in nude in the coming months and replacing my other bras.

      Great shape and support

      Really love the shape and support, and the soft mesh fabric makes it feel a little special.

      The Sieve bra has been my go to for the last 2 years.
