    Need one in every color

    The Sieve Non Wire Bra is my favorite. So comfortable and moves with me. Doesn’t roll up. I’m mid-sized and it fits so well. Just bought my second color.

    Best best best

    Best wireless bra ever. This was part my second purchase from Negative. The Sieve is my go-to. I am a solid 34B and this is one of the most comfortable and flattering bras I’ve ever worn. This is not a cami or a bralette, it’s a well designed bra that lifts and holds while being light and wire free.

    Thanks Negative. Love these!

    Love, had to get another

    I have this in black and wear it constantly, so I decided to grab one in nude too. So comfy with just a hint of sexiness from the sheer fabric
