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

Super comfortable and sexy

I have tried other non-wire bras and made the decision to never go back, but still struggled to find something that felt like it was giving me a little lift and support. The sieve fabric doesn't sag, giving the support and lift that I've been looking for all day and after multiple wears. It also looks super cute and sexy! I do prefer the slightly wider band of the silky-nonwire bra around my ribs (it stays in place and is a little more comfortable), but prefer the mesh of the sieve fabric. I typically wear a size 32-34B and got size 1, which fits comfortably on the middle hook.

Love it

Simple, sexy, and comfortable. It's so hard to find bras that actually fit me (I am a 32-34A and ordered a 0). I'm glad I found this and I will be buying it again in multiple colors!
