I love ballet outfits, some are expensive (depending on the materials used) but some of them are surprisingly cheap.

Take a look at this ballet outfit by Curtain Call:

The one downer is that there is only a limited number of sizes, I think size 20 is their biggest but I can just about squeeze into a size 12 - lycra/spandex is nice and stretchy.
