How to cover past abuse and self-harm scars for ex-roomates party?

Hey. I usually just put foundation or consealer on top of the scars and then they look a bit better. Just keep moving all night i guess..? haha. Oh, and do you have long hair?? If so i guess you could try covering up the marks with your hair resting on your shoulder or something? :) Hope this helped.. Good luck for tonight.! =D
