So, we are having a kind of rockabilly/pinup inspired wedding. My girls are wearing black swing dresses with red crinolines. I happened across these shoes today and fell in love!

My girls love them, I love them. The problems being: they are 5 in tall, they are $100. I would fell terrible about asking my ladies to buy $100 shoes. So, I am looking for something comparable to this style. My guidelines are: black, black and white or red, no higher that 4", less than $100. I would also prefer them to have some sort of ankle strap (I am open to no strap as well, though), I also am very attracted to peep-toes and bows and polka dots, but none of that is required either.

Help me! I know you guys can track something fabulous down.
