Our clothing is true to size, with the exception of Sully's Mandarin and East Bay maxi and mini. In our Sully dress, we suggest sizing up if you are a C or D cup to maintain a better true to size fit. In our East Bay, we suggest sizing down 2 sizes for a more fitted fit, and one size if you do not want as much fabric. If you have questions about specific styles, please email sales@victoriadunndesign.com and we will be happy to assist you.
