What to Wear

This is your excuse to buy or rent a new formal fit, rewear the bridesmaid dress you were promised you’d be able to wear again, pull out your tuxedo T-shirt, or see if you can find your old prom dress in your parent’s closet.

Current or throwback fashions are both welcome. This is a pick-your-era formal event.

Your ticket includes a silk corsage or boutonniere. A variety of colors and styles for both will be available at the door for you to select from upon arrival.

Food and Drink

There’s no need to sneak in booze. A variety of beer, seltzers, and canned cocktails will be available for purchase (credit card only).

Light appetizers, included in your ticket, will be available to graze on, but attendees should plan to eat dinner before arriving.

The event will wrap up at 11 p.m., but we’re not giving you a curfew. Your post-prom activities are up to you, but please plan ahead for safe transportation to a local bar, hotel, or home.

Entertainment

The night will feature a high-energy and interactive dueling piano show from Howl at the Moon. A drummer, guitarist and saxophonist will round out a full band covering a variety of genres you can dance and sing along with.

And just like any dueling piano show, the band will take song requests from attendees throughout the night.
