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)

Comfortable and Flattering

This bra is sexy yet comfortable. It's difficult to find a bra that is both. It's the first bra I've owned that provides both sufficient support without the straps falling down continually. I've worn it through active, sweaty motions and it's both cool (temperature) and stable.
