Gorgeous Vintage Formal/Prom Dress

(Last photo is old and unfortunately grainy, I no longer fit the dress and cannot provide any other pictures of it on) Condition: like new Faults: possible threading near the top hook on the back, easy fix. And I’ve noticed some pilling on the bottom which I’m too scared to go over with a trimmer. Soft and double lined, this is a slimming and flowy bottomed gown. She’s a size 1 but can fit a size 2 very well, spaghetti straps and an open back. There’s a very soft train made so that the heels can be shown but the ground is still being grazed at the back. The material is made to shimmer and shine like silk in the sun and has only ever been worn once.
