Boyfriend makes fun of me with friends...why? and what to answer them?

People can always make fun of the ones they don't understand, and in this case it's you. They're wondering why you just don't conform to their ways!! Dammit! But you won't. They're probably extremely jealous of pretty and well-dressed you are, and honestly, they probably couldn't afford the clothes/accessories, either--not that that matters. But really, you could try talking to them and explaining that it is annoying when they do this, and it upsets you. They might say they are joking or that they're not being serious, but honestly, do you want friends who make fun of you 24/7? I think not.
