Every man to his taste.
Prov. Everyone likes something different, and you should not condemn people because of what they like. (Can be used to remark that someone's tastes are different from yours, as in the first example.) Jill: Why don't you get some decent neckties, Fred? Fred: What do you mean, decent? My ties are perfectly fine! Jill: Oh, well. Every man to his taste. Ellen: People who like cats are much more discerning than people who like dogs, don't you think? Jane: Not necessarily. Everyone to his taste.
