If you didn't post your Halloween costume on the Internet, did it really happen? That's one of the existential questions we have to ponder in the modern age, especially when one is perusing the web to see what kind of costumes everyone in Seattle was wearing. As we did in 2014, we looked around to find the very best Halloween costumes that were "Seattle-themed" this year. Sometimes that's pretty obvious (The Gum Wall) and sometimes we used some discretion and leeway (The Grey Anatomy doctors). Below, check out the best Seattle-esque costumes we happened to find. If you know of one that we missed, by all means send it our way and we'll add it to the pile.
