Item Size: L
I bought size L instead of my regular S taking into account the sizing chart and some reviews, but not sure if it was going to be a mistake because I didn't want to have a bag. Happy of choosing the L, it is perfect for me, an M could have sofocated my chest. THe material is good and the style is wonderful. Just to point out it is a little bit long to wear with flat shoes if you're my height.
