We provide the dress.
You provide the personality.

We want your special occasion shopping experience to be just that - an experience. Our seasoned staff requires an appointment to try on but we encourage you to stop by anytime and browse. To book an appointment, please call us at either of our locations or Text 484-580-9417

We also require ALL PROM and HOMECOMING SHOPPERS be accompanied by a parent/guardian over 25 years of age because our gowns are very delicate and may require assistance to try on. Consume your morning coffee before entering the store. We have a no food/drink policy in our store for all guests. Even spilled water can destroy a dress! Thank you for understanding!
