1. have something the way you want or like it
fine, suit yourself, then
When you say 'suit yourself' it is usually used as a response to someone who has different ideas or desires than you do. This expression is essentially another way of saying 'do whatever you like,' but its meaning changes depending on tone. If it is said with a neutral or friendly tone, you are telling somebody to do what is most convenient for them. However, if your tone is irritable or sarcastic, you are making it clear that what is most convenient for them runs contrary to your own desires or beliefs. It can be used in either a social or professional context.
