Where can I find Chanel bags in Doha?

Hello! It's been only a couple of weeks since I've moved. So still new to my way around the city. The three big mall and the souq is about all that i've been to. However, my girlfriend will be visiting soon. I want to get her a good designer bag. I recall her talking about Dior, Chanel and LV bags. I see many ladies carrying these bags, but haven't seen the stores so far. Where should I go to? Thanks.
