Our best selling bra for a reason. 
Great shape and surprising support - no pad or wire included.

Free shipping over $75. Easy Returns.

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

LOVE at first wear!

I absolutely love this bra and I can't wait to add more to my stash. It could possibly be the most comfortable bra I have ever owned.

Thank you bra gods!!

Seriously though, I am a curvy 38DD, it’s really been a struggle my whole life to find a bra that does it’s job and also doesn’t kill me half way through my day. I want to be beautiful and look nice and feel sexy underneath, but also not suffer for it! Thanks Negative!!
