Forget to get a Halloween costume? Don't worry, here are some easy ideas.
Resident Evil features quite a number of characters you could cosplay easily but I'll highlight the classic Jill Valentine and the more recent Ethan Winters. For the former, there are two options of costume, the original Valentine boots, mini skirt, white top draped around the waist and blue top. Splash a little blood on your hands and your face and boom you're classic Jill Valentine.
The important part is obviously the trombone. I own a trombone, a strange flex, but I don't expect everyone to. Instead I suggest printing off a picture of a trombone and findingsort of instrument in your house that can sound appropriately terrible. Maybe a kazoo, that recorder you had as a kid, or maybe even a harmonica. Be the champ of any instrument you like and toot your little heart out.
