Know-How Exchange : Taglines/Names

I work for a nonprofit that typically just sells second-hand, thrift type items. But we have received 100 brand new wedding dresses from a company that went out of business, never worn, tags still on them, that we want to showcase at a one night only Bridal Fair type event.

We want to do like a trunk show, where we line up the dresses and sell dresses that are normally $400-$500 for only $100. It will be a one-night only event, like 5-8pm, to create a sense of urgency. We need a catchy name for the night. And then the challenge is to let people know these are new dresses, not second-hand dresses, so any ideas on how to emphasize that in the messaging and PR?

We will also partner with one local business from a florist, caterer, travel agent and party planner to help pay for advertising, so it's not just dresses, but that's what we want to emphasize.

Any suggestions on a name or ways to get our message across are greatly appreciated.
