    Sieve Non-Wire Bra in Buff
    Rated 5 out of 5 stars
    Favorite Bra

    As someone who is petite with a larger cup size (30F-32F), it's an unending hunt for the best bras - these bras were the first time I could wear non-underwire in my entire life. I own many of these bras - I started with the 1+ and 2+ sizes - which offer a thicker strap, a thicker band and a bit more coverage but now order the non "+" sizes and found that the regular size 2 is absolutely perfect for me. Obsessed with these bras!
