Halloween // Costume suggestions

My sister’s fiancee is not into dressing up too much but he has done a few costumes. All of them involved him wearing just a suit. I thought it would be hilarious for them to just always have him on a suit and do like a photo montage in a few years. He’s done squid game (the guy giving the cards and my sister was a contestant. Here are my ideas: men in black, fake Jim from the office (made even better because he is Vietnamese so it works well), Superman, James Bond…it would be ideal if it’s something they could do as a couple. Ideas?
