So my homecoming is in less then a month and I have no clue what to do with my makeup. I'm pretty good at doing my own, don't have no clue what look to do lol. And also, what is a good powder to bake/ set your face with that doesn't have flashback? I LOVE the airspun powder but scared to wear it since I've heard it does have flashback
