      Easy

      The size fit guide was super easy to use and was spot on. I am a little larger chested and I'm really enjoying this non-wire bra. It's fully support and sexy!

      All time favorite

      The Sieve non-wire bra is now my all time favorite! It’s like wearing sexy lingerie that is so comfortable & functional, you never want to take it off...

      The bra I have been searching for!!!

      I have been searching for the perfect bra--no underwear, no padding, supportive but still has that bralette feel--and this bra is everything I have been searching for and more! I'll definitely be ordering more colors in this bra and I can't wait to try other Negative products. Highly, highly, highly recommend!!

      I love the sieve non-wire bra!

      That's it, I'm done with all my other bras, this is the exact bra I've been hoping to find. I'm ordering 2 more after I finish this review.
