Sanctuary tunic, size Medium

Sanctuary tunic, size Medium, in 100% polyester. I really like this top and love the colors, but it is too large for me. I should have gotten a small. Measures 19.5” pit to pit and is 26” long in the front and 29” long in the back. Has side slits. If I could shrink it, I would keep it. Maybe someone else can wear this.
