Spoilers further down for Captain America: The Winter Soldier. But they're kind of obvious and most people knew it going into the cinema, I think. Phone quality photos, too.
I went to see Psycho in The Sugar Club for October's Film Fatale. I'm bad at putting together era-specific costumes, but I was happy with the dress and make-up for this.
Psycho gets better on rewatching, too. "My mother, she - oh, what is the phrase? - she's not quite herself today."
I spent Hallowe'en night running a pumpkin carving workshop at work. The general public are surprisingly good with knives! I was happy with my fake bruises, even if a lot of people didn't notice them. (I had fingerprints around my wrists - given that people didn't notice the one around my neck, they were probably an unappreciated effort.)
I like to dress up as something scary rather than specific characters for Hallowe'en, but Bucky Barnes's loss of agency and autonomy as the Winter Soldier strikes a nerve for me. No-one seemed to have seen Cap 2 whenever costume plans came up, but the gentleman in the off-license realised who I was once I asked if he had seen Captain America 2, as did a few other people at the party I went to. Only one person figured out who my costume was unprompted, but couldn't tell who I was under it - to the point of not being able to discern gender - so I think that's a reasonable success.
I think my costume was the right amount of effort + mediocrity. I'm also weirdly prone to letting the length of my hair determine my costume - see Harry Potter last year.
