Vibrant Silk feel Blouse

This is an absolutely beautiful blouse. Pictures really don't do it justice. It is a polyester but I had to doublecheck it wasn't silk! The colours are rich and vibrant. Looks fantastic with white. Only worn once. They only had the medium left so I thought I could pull it off but it was too to tight across the shoulders for me comfortably so alas I am parting with it!
