NC for this as I've discussed it with a couple of people today.
I've advertised 2 hallowe'en costumes on FB marketplace this week, they are character costumes from a kids cartoon. One boy character and one girl character, and the costumes are for ages 7 and 11.
A guy messaged me last night asking to buy them, and I agreed to meet him in a public place this weekend with the costumes. So far, so normal. Then he messaged me this morning to ask if it was still ok to buy the costumes and I said yes, then he comes back and asked "when was the last time the costumes were worn, if you don't mind me asking."
AIBU to think this is a really strange question to ask, and wonder what his motivation for asking is?
