Do you think im being a bit selfish?

She's worried obviously that your going to look much better than her, it's very obvious to me anyway because my sister in law did the same thing to my little sister, i backed out of the bridesmaid role because she was being too controlling. If I were you I'd have a serious talk with her and if she won't try to make you look you know more human and the way you feel comfortable, back out!! She's being selfish, not to mention making you grow your hair... that's not the way you wear it, who is she to dictate what you wear, I understand her choice in clothing but I don't see how she can make you change anything else... Maybe I'm just being odd but I'd be uncomfortable in the same situation...
