    Amazing

    So great, I ordered a size 1 and needed a size 2, so my friend took the 1's and now i'm ordering 4 more in a size 2. These are amazing! Can't wait.

    Prefer the triangle bra

    There was nothing fundamentally wrong with this bra, I liked the triangle version better - it was more flattering, so I returned the sieve non-write.
