I was in Montreal for the Just for Laughs festival and decided to check out Jeans Jeans Jeans based on the positive yelp reviews.
My friends and I (a guy and a girl) loved this place - amazing selection, prices and service. The woman who was helping me nailed my size just by looking at me and was great at helping me navigate the store and find things. I ended up coming out with two pairs of Second Yoga jeans at $75 a pair, which is JJJ's regular price and much less than what other places charge.
I can honestly say that all of the positive reviews here are not exaggerations - this place really is that good - and I will definitely return to Jeans Jeans Jeans whenever I am in Montreal.
