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 for bridal gown and ballgown shopping, and would highly recommend one for prom as well. To set an appointment, please call us at either of our locations or fill out the registration form!

We also require ALL PROM SHOPPERS be accompanied by a parent/guardian over 25 years or age because our gowns are very delicate and may require assistance to try on.

Shop it like it's hot.
