Happened across online information that Yorkdale Centre has a partnership with a community organization until March 31 to accept gently used prom apparel and accessories.

Details here:
NEW CIRCLESFor a consecutive year, Yorkdale has partnered with New Circles Community Services’ Prom Boutique, a program that enables graduating high school students across Toronto, who may face economic barriers, to be fully outfitted for Prom at no cost. Style Concierge representatives will be accepting gently worn formal wear that will go to low income families seeking special occasion wear for events such as prom and weddings.
From March 5 – 31, you can help stock the New Circles Prom Boutique by visiting CONCEPT and bringing in new or gently worn dresses, shoes, bags, jewellery, suits, shirts, pants, ties and new makeup.
