Winter Jackets for Littles

Where is the best place to get one? My 9 month old is almost walking and wears size 12-18 now. We are in Canada so it will be freezing in a couple weeks. I am having the hardest time finding a good winter jacket that is not too childish looking. I just want grey, black or muted pink. Old Navy and Joe Fresh have the best picks so far but want to make sure I'm not missing anything. Carter's & Children's Place have nothing.

My mom lives in the US so US suggestions are fine, she is coming in a couple of weeks and can bring it.
