Fit

  • Size Chart
  • Use this as a guide. Preference is a huge factor — the benefit of a non-wire is they're super flexible, so you will likely fit in more than one size. Like a looser band? Size up! Like less coverage? Size down! Still unsure? Try two sizes :)
  • *Note, our Sieve Non-Wire doesn't have the same wide band as our Silky. As a result, it'll likely feel snug the first few wears. Don't fret — it'll stretch a bit with time.

Fabric + Care

  • Size Chart
  • Made from a sheer Belgian power micromesh — nipples are visible
  • 74% Polyamide (Nylon) 26% Elastane (Spandex)
  • Hand wash in cold water, dry flat

Where has this been all my life

The most supportive and comfortable bra which is also sheer and sexy. I'm a 34G, and this fits me beautifully.

Almost perfect

This is the best fitting bra for me out of all the Negative bras I have tried. Support is perfect and comfortable. I’m usually a 30D, the size chart has me at a size 2, but the 1+ fit me much better. If there was a 0+ that would be even better so I could start with the loosest hook & be able tighten as it stretches. As it is, I start on the 2nd to tightest hook so I don’t have far to go.

With the + size, the piping on the edge of the bra does not leave a dent & there is no spillage. LOVE the mesh here in hot FL.

The wide band and wide-ish straps make this easy to forget I am wearing bc it is so comfortable.

The mesh really adds style. The silky bra is the same cut but without the mesh I feel like it is too ‘18 hour Playtex’ looking.

I really wish there was extended sizing for the triangle bras. I love how they look but my boobs creep out - need just a little more cup!

I love this bra! It is comfortable and the size is perfect. I used the size quiz on the site and it matched me my perfect fit!
