Lovely Marc Jacobs jacket

Here's a picture of the most inspiring coat I've seen in a long time. I've got yards of the perfect heavy vintage wool to make a similar one out of, I'd lengthen the sleeves - I want to make it good and warm and I'm tired of chilly arms - but besides that I love it. It's perfectly versatile, whether worn over a little dress, or with old jeans and sneakers. All my (2) coats have to be worn with fancy things or I look confusing. It's a little frustrating on the weekends when I want to slouch around.
