So my sister just kind of assumed she was my MOH -- which I'm fine with but would have prefered my bf. But I just asked my bf to be my bridesmaid (I'm only having those 2). Anyways I'm looking at booking a hair dresser / make up person, but my sister said that she doesn't know if she wants to get her hair done .... which i guess i wouldn't mind if she knew how to do her hair so it looked nice, I mean not nice but something other than a pony tail or straight .... How do i approach this? Do i just pay for her to get her hair done?? or just say whatever?
