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 :)

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

This bra is both sexy and comfortable, and the mesh is surprisingly soft and stretchy. Absolutely love it!

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.
