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.

Perfect in every way

Love this bra! So comfortable. The wide band doesn't dig into my ribs. And the low v shape doesn't peek through a button up shirt. I'm a 34A and bought the size 1 and it's just right.

Still deciding

I like the thicker band around the rib cage. I am a 34DD and find the other non underwire sieve better as far as support in the cup. In a perfect world I would combine the 2. It's still a great bra for being around the house.

not a great fit for me

I really loved this, but couldn't get a good fit. I'm a 32DDD and thought that it could work, but, in the size 3, it's not supportive enough with the full lengthening of the straps and when adjusted to the shorter, the bra does creates a spill over, which is common for fuller breasts. I might try a larger size,but not super optimistic for my shape.
