Travel-friendly Halloween costumes
I'm going to be in London for Halloween this year, as I'm doing a multi-week trip to Iceland/UK in late October/early November. I'm packing very minimal, boring clothing as I'm only bringing a S19 and SCB. What are some good Halloween costumes that don't take up a lot of room? I may just do what I did the last time I needed a costume abroad (buy some stuff there and leave it with my friends when I go), but I was wondering if anyone had any go-to travel costume ideas.
