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.

Superb

My first Negative purchase won't be my last. I don't like padded bras nor underwires but I need support. So, I tried this style and it works for me. I like the colors available and several styles that enhance my figure.

Favorite

This is the only bra I ever want to wear. I love the feeling of being FULLY supported without the underwire. I never have to adjust my boobs throughout the day, just all day comfort. AND, it is a bra you can be comfortable in all day at work, but is actually so sexy it’s perfect for nights out (or in). The little black dress of bras. My point is that I used to feel like I had to choose between comfortable/supportive bras that I didn’t want anyone to see me in, and sexy bras that looked great but felt awful. The sieve triangle bra has changed all that, and that’s why this review is so long. I’m genuinely grateful! It actually IS the most perfect bra I can imagine. Thank you for this bra. Buying a 3 pack in every color next time they’re available and never looking back.

(I wear a Negative Size 3, my trad size is 36D)
