Addition Elle and Penningtons will be Ok. There is an outlet with change room at Dundas past Dixie but before the 427.
Voluptuous is the best. They just moved to Queen St. Check out their website. I love their stuff.
I also LOVE Torrid. It's a USA company so I shop online but their clothes are amazing and prices are fair. Shipping will cost though unless you trek down to Buffalo to the Walden Galleria.
