If you want something short and flirty and fun, try Forever 21. There are tons of them in Toronto and it's beyond cheap. in fact, you could get a really hot dress, shoes, jewelry AND makeup and probably still be under $100.
They don't have anything long, but if it's for a grade eight graduation, short is probably better anyways. It's always better to dance in short dresses and then you can show off awesome heels and stuff.

I'm not sure how good it is, buut it is an option!
