Say Yes to the Red Carpet Dress! - POSTPONED

Teens can come to the library and "shop" for free prom clothes.
  • Come "shop" from our curated selection of stepping-out-styles.  Does that sound like a made up term? It kind of is… it’s hard to describe the actual amazing range of items available to you for FREE at this fun program. You’ll have to see for yourself and do the leg work it takes to discover the ultimate, most-one-of-a-kind prom-wear out there. Bring all your friends and have fun with us!
  • Not going to prom? But still want to look amazing? Come shop the boutique for a look to help you feel your finest while living your best life.
  • For those in grades 6th - 12th only.
  • No registration required.

The Friends of the Longmont Library generously support library programs and services.
