Proof is the couture studio of designer Jessica Firestone, located on Queen Street East in downtown Toronto. I create custom garments with a focus on beautifully fitted, corseted designs, using only natural fibers and traditional couture craftsmanship.

Every garment begins and ends with an in-person fitting. Across a series of private appointments conducted at my studio, each piece is sculpted directly on your body, using my expertise and your personal feedback to create a garment that feels perfectly yours.
