Absolutely Stunning Formal Gown 100% Silk Sequence Shiny RN # 50782 No size found on this item. It is closest to a size 5 or 6. See measurements. I have looked this up online and found only Adrianna Papell that looks like this one. I do not have a name brand on this one. I am listing it as Adrianna Papell since it is the only one on when I google it. The pictures do not do it justice. Measurements are as in pictures.
