I wore this Oleg Cassini One-Shoulder dress for my 10/13/13 wedding. I bought it in a size 2 and then had subsequent alterations (upwards of $500), including tightening pretty much all the areas and also hemmed masterfully. There are so many beautiful layers to dress and I felt like a complete princess. I received SO MANY compliments and the dress really just looked STUNNING in person. See for the stock image.
I am 5' 4" and wore 3.5" - 4" heels for my wedding day. This dress will fit a petite/slim female. I normally wear size 0 - 2, XS - Small in street clothes and dresses.
I also have a medium-full slip, which I paid additional for, this one is in a size 6, and fit well on me with lots of comfort.
