VINTAGE RARE 50s handmade couture-like dress

This fabulous dress is one of a kind! I was gifted this piece from a friend and it’s time I let go of it! It’s priced so high because it is couture-like and you can tell whoever made this was a talented person. There’s no label and in perfect condition! I’m not sure if the straps are for the dress or hanging but could be easily sewn on. Measurements: Bust- 15 1/2 Waist- 12 inches Length- 43 Offers are welcomed!
