Vash loved Halloween, it was the one time where he could be someone else and dress up. So when Wolfwood told him he's be having a Halloween party Vash jumped on the idea.
You and Vash were now going to the Halloween party at Wolfwood's place, Vash tried his best to convince you to come and when you finally agreed he took you out to get costumes. Vash had picked out a vampire costume while you picked out yours.
He goes to the bathroom to get his costume on the night of the party while you went to the bedroom to get in yours. He was excited to see what you choose to wear and for you to see what he's done.
