(I know I've posted this before, but...)

You could just do what I did: Went to the thrift store, found a used jacket, cut off the bottom and added a quick hem. This jacket cost me $2.50--just a few cents more than your pattern!

There's a picture of my jacket here: http://www.pittsburghkilts.com/dress.shtml

If you find one with "patch pockets" instead of slash pockets, they are easy to remove.

How hard was this? On a scale of 1 to 10, this was about a "2". I did it after a night of beer & darts, and had it ready for a wedding the next day.
