That looks like my sister. She got paid $260 (she had 3 different deals going with 3 different people) to wear a dress to her 8th grade graduation. And wore big black combat boots under her gown at highschool grad.
That's the way to go. Why wear fancy, uncomfortable shoes when no one's going to see them anyway? Every time I went to a dance in high school I wore my regular sneakers under my dress.
