My classmates came to my dormitory to try on my high heels without my consent. Then wear it off. How to refuse similar things to happen again?

First of all, I understand your feelings at that time. I wonder what is the relationship between your classmates and you? If they are all good girlfriends, just make a joke to remind them! If he doesn't have a good relationship with you, there is something wrong with his character. I suggest you don't leave too much feelings, just make it clear to your face, ask the reason clearly, and then give a serious warning!

I don't know if this answer is ok, I hope it will be adopted! !
