size 8-10. The label is marked Size 14. Here is the description from the seller that I purchased the dress from: Authentic Vera Wang Gown- purchased in July 2007 at Saks Fifth Avenue in Dallas, Tx. I wore it to my own wedding last October and now feel I need to pass it on to someone else as my finances need some help! Please read description carefully as this dress was altered to fit me-which included Cutting the hem-which cannot be lengthened back!! The dress is a size 14- so I think this would easily fit someone who wears street clothes size 10-14. It would be very difficult to let out as the dress is layers of pleated English Netting which is very fragile! I wore a Spanx undergarment and felt great and comfortable all night. (I highly recommend the style that looks like bike shorts up to under your chest-it didn't roll down and smoothed everything out nicely!) I ended up wearing a little silk jacket over the dress-which is why I'm not using my own photos. I will include the beautiful champagne-colored grosgrain ribbon that came with the dress. I also have the Certificate of Authenticity and Saks Garment Bag. This dress is great for its flattering fit-as well as the many looks that could be styled. I was going to wear the ribbon tied on the side in front with a silk flower or brooch pinned there-but the woman in the article wears it tied in a sweet bow in the back-which is another option! Ok- more info. Alterations were a bit tricky but my seamstress worked some miracles! There was no way to bustle the dress when I purchased it. I found out through Vera Wang's rep that the dress was meant to be "French Bustled" which means several layers of bustling. There are ties under the main undercoat, very tiny hooks and loops for the next layer, and then three buttons to tie up the rest. My little jacket covered the buttons-as I believe would the sash if worn. They are hardly noticeable as they are. The dress has been professionally cleaned-although as the photos show the dirt stains on the underneath part of the hem that could not be removed. There is also a small spot near the hem. There are also two holes where the netting was snagged at the edge. If you step back and look at the gown-these things are unnoticeable. I'd be happy to send you some more photos if you like- please email me.There is an elastic strap inside the dress that really pulls you in around the waist.
