I wasn't googling "Islamic" because it isn't necessarily Islamic clothing. Following a number of those links, they are specifically formal, religious wear (as one might expect) and tend to be formal or 'fancy'. I'm looking for everyday wear.
Thanks for the idea, though. I may visit some of them anyway to see if they have anything.
Yes, I have tried googling "toronto afghan clothing store", "toronto pakistani clothing store" and "toronto afghani clothing store" and most of the results are formal wear stores. I also searched kijiji and craigslist. Kijiji came up with almost entirely women's bridal wear and craigslist had some kids clothing and women's clothing.
