They dont know how to apply it properly. Yes i wear makeup all the time. I wont leave the house without it on. BUT i wear it naturally most the time. Its all about application. NOT jersey shore style :p
It all depends on how they see themselves, especially when they look onto the mirror. If they know the proper way to apply the makeup it does enhance their looks. It is all about the girl feeling good about herself.
People who wear makeup are not stupid . I wear makeup almost all the time and i do it because i think it's fun ! Now i don't cake it on my face, but obviously it's noticeable ! The purpose of makeup is to enhance someone's natural beauty . Even if ugly people wear makeup, who cares ! If they believe they look pretty with it on . . let em . Wearing it doesn't make them look ugly so people can all stop commenting that !
