Ordered down a size in cup and up a size in circumference, so a 36a for daughter. Cups still huge and there is no smaller size. Not sure we really needed to upsize a circumference.  She is normally about a size 3 or 34b on the top.  She also thought The Lace would have been itchy. Was hopeful that it would work under her formal needing a strapless, lower back bra. There are free no complicated returns, and I thought it was a well-constructed garment with just enough padding to conceal any nipple showthru.
