For me, I'm not old enough to drink and not that it would interest me anyways, but 2 cocktails is an eyeshadow or lipstick. Also I don't smoke or do any of that-makeup is my indulgence. Like previously said, makeup is a creative outlet, it is my only creative outlet, so I justify it that way. Also potentially down the road I might want to go into makeup art so that's the other justification.
That being said, I am trying to tone my spending down because I want to save up to move out of the house, I would like to get more jeans and sunglasses, and just have money in case something were to happen.
