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.

The best bra you'll own!

I've tried a lot of bras and this ones takes the cake. Super comfortable even for a slightly larger chested person.

Best non-wire bra I’ve tried

Best non-wire bra I’ve worn because it offers enough support and shaping without wire or padding. Great for summer and wearing with looser clothing. I think it looks nice and I like the minimal tasteful design. The only thing I don’t like is that band tends to bunch and wrinkle and needs to be straightened and smoothed out after several hours.
