Vintage Floral Flower Off shoulder Ruched Puff Victor Costa Kentucky Derby dress

I think this dress is a size small. Model's Measurements: Bust: 32in. Waist: 25 in. Hip: 33 in. Height: 5'4. This dress is vintage! Has signs of wear but in decent condition. It is like a sculpture for a dress. The back bow layered part with the fake flowers on it is really pretty. Please comment for questions and concerns! Thanks!
