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
  • A soft silvery cloud lunar dust baby bunny ears tone 
  • 74% Polyamide (Nylon) 26% Elastane (Spandex)

So comfortable and great for nursing

This is the first bra I've had that is comfortable, sexy, and convenient to breastfeed in. And it's not the nursing bra, just the Sieve Non-WIre. The stretchy material makes it easy to nurse my babies and I get to feel attractive at the same time. I always avoided unpadded bras, because I felt they lacked the shape I wanted, but somehow this bra creates a great shape. Love everything about it!
