Congratulations, you’re officially a moron.
I don’t know why someone would think this is appropriate to wear to a high school prom. I’ve always said when you’ve got it flaunt it, but only when you’re old enough to have figured out what ‘it’ is and you’re out on your own paying your own damn bills. I can’t imagine what her mother was thinking to allow her out of the house in this. If I had a daughter her age and she wanted to wear that napkin to the prom, I’d probably put her in a headlock. Maybe I’m being too harsh, but I can remember a time when Prom was a classy event. Can this even be called a dress?
