You can wear it warmly by layering. It's an A-line, but the length isn't long, so I think you can wear it without feeling restricted, and the line is barely noticeable. For me, with an M-size frame, the sleeves come to about the middle of my upper arm. How about for a vintage or used clothing style outfit?
