Vintage 1950’s/1960’s yellow dress that looks like Belle’s dress in beauty and the beast! Never worn. Has small spot on front from storage that should come out by someone that knows how to treat the fabric properly. It hasn’t been attempted. Bought at Bullock’s Wilshire in Los Angeles by my grandmother. There are no internal tags. Zipper is not up in back while on mannequin. The mannequin is just too large. Zipper is up in other photos.

Please let me know if you need additional sizing :)
