Volcom women’s pull over snowboarding jacket

Volcom women’s fern insulated pull over jacket in size medium. This jacket is in perfect condition with no stains or wear. I used it for one season and realized that it’s a bit too big on me. I loved the warmth and style of this jacket but I’d love to get my correct size. Pit to pit measurement: 22.5 inches Top of shoulder to bottom: 28.5 inches I have attached all details and specifications!
