Oleg Cassini Ivory One Shoulder Ball Gown Wedding Dress

Oleg Cassini One Shoulder Ball Gown Wedding Dress NOTE: I have no idea what size it is, and it has been altered. The dress is from 10 years ago, it has been professionally cleaned and packaged for storage. I lost the receipt and don't remember the size of it. Might be anywhere from 10-14 but has been altered. I would estimate at that time I was 160lbs, 5'6. I have the ball gown slip also, listed separate.
