I did not have it custom sized, but I did have it "lace up" instead of zipper, so that I was able to make it fit my curves perfectly :)
The dress is absolutely beautiful. The top is boned and padded so undergarments are not required. the whole bodice is boned with so much quality. The ruffles are quite flattering and well done. The skirt has so many layers! It has a double layer lining, a tulle layer and multiple organza layers, but it's not all that heavy.
