Queen & Dundas are parallel to each other.....I'm assuming you mean near Eaton Centre or Queen Street?
If near Eaton Centre, I would check out StyleExchange near Yonge + Queen (they carry Miss Sixty, Diesel, Mackage, Juicy, etc.) and Blue Marine (they also carry similar brands along with Soio & Kyo), Aritzia, or Mendocino in Eaton Centre. Some chain stores: Mango, Zara, Club Monaco, Banana Republic.
Thanks! We ended up going to the Eaton centre then down Queen street. She bought one little jacket thing at H&M and then as we were leaving saw this coat in a shop called "c-squared" and it was awesome so she bought it.
Yeah I have no idea where the streets are. This has probably been my most intense Toronto trip as for knowing where I am in the city.
