Perfect dark wash denim vest

Perfect dark wash denim vest. Kind of works like a corset. Brand is FURST Premium. Would be cute with a cropped puff sleeve blouse under. Marked a size 8 in women's but runs small. I usually wear a medium in women's and it was really tight. Would suggest for a small which is why I'm listing it as a small.

Measures 17 inches pit to pit (34 inches), waist is 15 inches (30 inches) and it is 18 inches long. Please compare measurements to your own to make sure it fits. Used item, has been washed.
