Yikes! I've been so busy since Fan Expo that I neglected to post my photos from the Thor: Ragnarok costume exhibit! Thankfully going to see the movie last night reminded me hahaha. I'm not planning to make any of these costumes myself, but maybe you will find these references helpful? The whole collection is on this page here, just a couple of highlights below, and feel free to message me if you want larger versions of any particular shots!
