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

This Bra is Magic

I am completely in love with this bra. I don't know what type of magic fabric, structure or design this is but it's amazing. I am a 36DD and have tried countless bralettes/non wire bras and none of them have ever given me support or held me in. This bra does it all and looks great under my clothes. Looking forward to ordering more colors. For someone with a large cup size and smaller band size the adjustable band makes all the difference.

For reference, I am 5'8, 150, size 6/8, 36DD and I ordered a size 4.
