I wear a size 32D normally in bras, and bought that size in this one because it's the smallest band size they offered. The sizing information did say to order down, and I wish I could have. I wish there had been a 30 offered. The 32D works, and I will keep it because it is a comfortable racer-back bra, and I don't have one of those, but it does feel more roomy than my other bras. Less secure and more bouncy. So, definitely order a band size down if you can.
Most comfortable racerback bra I own! I ordered my regular size (unlike style 1485, where I followed Nordstrom recommendations for sizing) and it fits perfectly. Have it in both colors and couldn't be more pleased.
Loved this bra- unbelievably comfortable!!! But when they say order one band size down and cup size up, they mean it. Unfortunately I am a 34D and the 32D was too small- but it was so comfy I almost kept it anyway!
