I was He-Man on Halloween as an 8 year old. My little brother was Orko. It was pretty awesome.

I did some reenactment as a early American colonial settler for a whole expo in a town event. That was pretty fun! Outside that I’ve only helped friends with their actual cosplay. One friend did a league of legends character (IDK the name, I don’t play) and one did reinheart from overwatch. And another did a tavern wench.

Unfortunately I don’t have any pictures in hand. I may cosplay myself soon though. Unknown

Does Halloween count?

I’ve done Johnny Depps character from fear and loathing in las Vegas for something

Nerdy from Jurassic Park.

Jack from The Titanic when I went to a haunted maze at the Queen Mary one year.

I cosplay as someone with their shit together most days.

I have a couple times.
My favorite was as a Katamari - Was standing in a giant Hoberman sphere on a rolling cart. The structure was covered in a sheet and the sheet was covered in whatever junk I could find that would fit, but especially stuff from the game. Even had a life size Prince of All Cosmos trailing behind it
