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

A+

I hate wearing bras and rarely find one I can tolerate. This bra fits great, is very comfortable and is very light weight.

Unbeleivable comfort

During COVID, I probably ordered 10-15 bras from various companies Every single one got sent back except this bra. So comfortable that you hardly know you are wearing it. Usually the first think I did as soon as I got home was take off my WIRE bra. Not sure if I will ever wear a wire bra again. The Sieve could stay on all night. For reference, I wear a 36 DD and ordered the Large. Fits perfectly!
