Hair and makeup drama

My sister is bitching about who I chose for hair and makeup. When I wanted help looking in summer she was too busy or preoccupied. Now she's saying its ugly bla bla. I already signed a contract. Now she is stressing me out. Who did u guys use? I'm feeling all disheartened now and in a bad mood. Maybe I rushed into it from 1 trial? I mean can't most hairdressers replicate the style anyway. Ah sigh
