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 :)
  • Adjustable straps and hook & eye closure in the back
  • *Note, our Sieve Triangle Bra is an intentionally lower coverage in both the cups and the sides. Wide plush elastic band is extremely adaptable.

Fabric + Care

  • Size Chart
  • Made from a sheer Belgian power micromesh — nipples are visible
  • A caramel-y sunrise desert sands affogato tone
  • 74% Polyamide (Nylon) 26% Elastane (Spandex)

New Favs

I love this style for low cut tops. It’s super sexy too. I took off one star only because it’s a bit smaller than the sizing guide led me to believe.

Just what I was looking for

These bras are more supportive than other bralettes I’ve tried. Very impressed. The size I bought (3) is too small in the band. Unfortunately the same pack is not available in the next size up. Exchanging for various other styles.
