These shoes are by far one of my favorite pairs of work shoes - BCBGIRLS Black "Katchen" Pump. They are classy, modern and chic. This shoe is a leather upper with a 4 inch heel and a man-made sole. I love this shoe for the simplistic style and the high heel. Since I am barely over five feet tall I'll take any extra height I can get. I can't take full credit for these shoes either, my good friend Margaret had a pair and I love them so much that I wanted a pair for myself.
