Here is a fun tutorial, though I am not sure on how practical it is. Unless, of course, you are just coming back from an excellent Italian dinner and have to remove your belt because your tummy is so big.

While I am not sure about how practical this tip is, if you are willing to go through the effort, the result is as cute as it can get.
