First off let me say that Ren R.'s review has some erroneous facts within it. "Leo Boutique is one of the few boutiques left in Calgary after the recession". This statement is simply not true, as more boutique style stores have opened in Calgary over the last two years or so than ever before in recent memory. Shops like Brooklyn, Henry, Bloke Clothing among others, as far as I know the only boutique style store that has closed because of the recession is Smyth and Kang.
More to the point, Leo Boutique is great, has many brands and styles not often found in Canada such as Acne, but also featuring more common up and coming brands such as Nudie and Cheap Mondays and other great Swedish brands. Great service, the decor is also very simple but equally elegant. This is one of 17th ave's best
