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

  • Made from a sheer Belgian power micromesh — nipples are visible

Love it!

i’m a 34 DD and a big fan of bralettes, i only wear real bras if absolutely necessary (so not often) this style is perfect for casual/everyday wear under pretty much any shirt. obviously it needs to be adjusted throughout the day as you lean over and whatnot but i don’t have any crazy side boob spillage like out of some other bralettes! and the straps stay put without digging into my shoulders

I f-ing love it

I absolutely love this bra, it’s so comfortable with the right amount of sexy. I can’t go back to wired and padded uncomfortable bras. Do yourself a favor and buy this bra, your boobs will thank you!

Only Bra I Wear

I am a 30D--so finding a bralette is next to impossible for me but this one is as close to perfect as it gets! I ordered a size 1 in both the Sieve non-wire bralette and the Sieve Triangle and i will be honest i like the Sieve Triangle better. This bra is comfy enough to sleep in and sexy enough to wear on a date. I am probably going to order a second one soon because i just wear this one so much! If you have a small ribcage and bigger breasts this is a bralette worth trying!!!! It is seriously one of the only ones that works for my size. The only recommendation i would make would be to make one more set of hooks on the back because i feel like over time i will need to tighten it. Highly recommend!
