Tahari cocktail dress

Gorgeous and sexy Tahari dress. It is fitted both front and back. Fully lined. From pit to pit it is 17” Narrowest part is approx 14.5” Widest area is 18”. Length approx 36” Back invisible 21” zipper and hook and eye. Not sure the size is accurate because I haven’t been a size 4 since my early 20’s. ☺️ I think size 6 would be more accurate but go by the measurements.
