IF YOU ASK SOMEONE FOR A HUG, AND THEY SAY NO - DON’T YOU DARE CALL THEM RUDE.
This. Its happened to me so many times. Please don’t be offended, but I do not allow strangers to touch me. Even close friends cannot hug me in cosplay. I put lots of time and work and money into my outfits, and I never allow hugs.
They flocked to you like moths to flame. I don’t understand their logic, let’s ask someone in a delicate costume for a hug and then get mad when they turn us down.
Or you could just explain that your costume is delicate instead of saying no. Then maybe they’d respect your reasoning and you wouldn’t be coming across as rude. Rude.
