Well, there are stores where I live (which is quite far away from Montréal, heh) but as I said, I'm not yet ready to go in and really shop. Or at least not go full-on. But even so, I really want to have something to wear that I like, at least at home, so the Internet is the way to go.
Thus far, no website except Yesstyle (whoo@those shoulders) seems suitable... And unfortunately, my friend is from Europe and none of the stores she visits will ship overseas. Add to that my crappy research skills, and you get a pretty confusing situation.
Anyway, if anyone else has ideas, I'll be happy. In the mean time, I think I'll figure out a way to get my measurement checked, and then... Well, I don't know, I might just try something from Yesstyle anyway. Maybe, as pretty said, since it's the shoulders, they can stick out a little through the sleeves and it won't be the end of the world. Or maybe I'll find a top with a closer shoulder width to mine.
