    Once right size found, pure satisfaction

    I loved how it fit -ALMOST. Ordered a size 2 and I couldn’t believe the comfort and natural support until I noticed a bit of a pop up from the top of the bra at center. So I ordered a 3 - AND NOW MY LOVE IS STRONG AND CONSTANT!!! And my ‘girls’ are singing.
