Has not been altered. Wore it for my wedding in Paris in May 2010 and it has been professionally cleaned. If you are seriously interested, I will take some current pictures (as I recall, there may be some mild discoloration at the hemline from walking down the streets, but you could just have it hemmed. I'm 5'9" and it was floor length, so you might need it hemmed anyway.)
It's a really gorgeous dress. I loved it (as you can see in the picture).
Serious inquiries only please, including best offer (not binding offer, just what you would offer if dress is as described) - I'll have to take the gown out of storage to take current photos.
