Recommended size was Medium, but based on reviews, I ordered Medium and happy I did! If I had ordered Small I definitely would have returned it. This is definitely an Small, button front sweater (!) that is thicker medium weight yarn but perfect for chilly weather and for people who don't like feeling constricted. I think it's too thick~heavy to wear under a vest or coat but perfect with a long sleeve shirt ~turtleneck, pants, or dress, and boots then throwing on a scarf for work or play to complete your look. Since it is oversized it's more casual than dressy but maybe with it belted it'd look dressier.
