My MOH's sisters are about to finish cosmo school and get their licenses. I've seen the hair and makeup they did on a friends recent wedding and wasn't impressed at all. But my MOH is assuming that I'm using them. I tried to joke that I have to use my hair stylist because I've been using her for 8 years and she'd be crushed if I didn't. But I'm not sure my MOH got the hint. How do I tell her I'm not using her sisters without coming off mean?
