Formals XO

Formals XO The ONLY store with gorgeous Prom dresses at King of Prussia Mall. Check out our other location at Oxford Valley Mall.

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 our registration form! We also require patrons be over 16 or accompanied by a parent/guardian because our gow

ns are very delicate and may require assistance to try on. Jovani, Sherri Hill and Top 10 Prom are among the dress brands we carry.
