I’m not on dating apps, so perhaps I don’t know all the protocol, but if I see someone dressed for fishing holding a fish, I don’t automatically assume they always dress for fishing. If someone is dressed up fancy, it could have been taken at a wedding and no one would accuse them of deception if they didn’t always dress up in wedding formal, no?

OP could put a text disclaimer in the post: “The pictures don’t represent how I normally dress. I very rarely dress fancy.”
