Someone else on here already beat me to this refashion. I'd seen these long vest-like things in places like White House Black Market and thought it would be pretty easy to do it yourself from an oversized men's suit coat. Well, everything takes longer than you think - there are a lot of seams on a suit jacket and they're not always where you need them to be. But it wasn't too bad.
Now I would probably wear this to work with a white shirt and black skirt, but I'm out of town and don't have those with me at the moment. I also have some nice sleeves left over to make a purse, so you may see that in the future.
