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 shadowy twilight taupe with a hint of amethyst and contrast black trim
  • 74% Polyamide (Nylon) 26% Elastane (Spandex)
  • Hand wash in cold water, dry flat

Most Comfortable Bra I’ve Ever Owned!

I’ve spent the pandemic wearing sports bras. Transitioning back to work after wfh for over a year, I wanted to find something that would give me more shape, but still be comfortable throughout the day. This is that bra! While it’s not the bra I’d choose for high-impact activities (I’m a 34D), it still gives me so much lift and shape and feels like I’m not even wearing a bra! The braless life is the good life!

Supportive once you find correct size

After a few false starts trying to find the best size, finally landed on the perfect one. Will be buying a couple more asap. My only issue was the “size guide” isn’t really accurate for larger chests — I’m a 28G and the 3+ is perfect (it recommended 1+ which was way too small in cups)
