What's more awesome than a sweet dress with Superman fabric? One with a cool "Super S" shaped cut out in the back like this one by Cation Design. You can learn more about making your own and see more pictures of the finished product at the link.

I see so many dresses like this on etsy, and very few bother with the details. Take the extra step and purchase extra yardage, and make the effort to complete the character.
