    Fabulous!

    I found my new bra and undie company! This bra is super comfortable. I had purchased a size 2 which fit but was a little snug. Requested a return which was super easy. Also got the matching thong underwear, also super comfortable. Looking at my second purchase already.

    This is so comfortable, fits nicely, and the band does not dig in. I am typically a 38D and got a size 5
