Is this semi formal enough for pref night?

Why exactly are you still here arguing that there are no other places to buy a dress in your town? Okay. Woah is you. Wear your dang dress. I bet ten bucks that any of us in this thread could find you a more appropriate dress in your town in one afternoon, but we aren't the ones who have to wear the dress. In the end, it probably doesn't matter. You aren't going through recruitment at a competitive school, the dress you wear likely won't matter. If you don't get a bid because of the dress you wear for prefs, c'est la vie.

BTW, wrong word choice is not grammar. Reservation doesn't mean what you think it means, but prerogative was the word you meant. Grammar is using proper rules of English not picking words with the correct meaning. Use smaller words to make your point if you don't know the right bigger word.
