Curvy Kate Response: This bra is made up to a size 40J, in order to be supportive and fit well Curvy Kate added these seams. The seams are designed to give the cups the added support need for larger cup sizes.
Curvy Kate Response: We are happy to hear that the bra runs true to size and it provides great support for you as a GG cup size. Since you are experiencing issues with underwire we would suggest trying to wear it on a loser hook making the band less snug around. If that does not work possibly going up a cup size to an H may resolve the rubbing issue.
