You may not know much about makeup, but you know more than your boyfriend.
Makeup artist Kandee Johnson met with boyfriends and girlfriends to allow the guys to pick makeup for their ladies. Johnson met with the boyfriends individually, then made up the girlfriends, and reunited them so they could see their looks. While the boyfriends had mixed reactions, the girls were pretty much uniformly horrified.
I learned a few things from this video: men don't know anything about makeup and hot pink lipstick looks trashy.
Okay, okay, sorry to generalize. I'm sure some women can pull off hot pink lipstick and some men do know that.
