Serious question for girls

Hi girls I have a serious question for you regarding wardrobe attire for parties. When you wear a super tight skirt to show off is it common to not wear any panties to avoid the panty lines? Have you ever done it? Does it make you feel naughty when you don't wear panties? Has anyone ever saw anything on accident when you weren't wearing panties? And how did it make you feel or how did you react when you got caught?
