Now I don't know exactly what you mean by corset, if you mean just it being shaped like a corset on top, or actually have the criss crossed ribbon. However, for the first type, I've seen plenty pretty much everywhere. In fact, I bought one off of the American Eagle website, the top was corset-styled, and the bottom was flowy to the knees. You can find such dresses at places like Forever 21, Sirens, Suzy, Macy's, Laura, Costa Blanka I'm sure I've seen the ones with the criss crossed ribbons at Sirens and places like Stitches and Urban Planet before.
You could try forever 21, if you have one in your area.
Possibly go to the mall and look around.
Anything that is mainly knee-high length and doesn't look like it'll be seen through your gown.
If you have thrift shops, for possibly a cheaper price, if they have any.
