Is this shit normal stuff to be asking someone before a wedding?

My fiancé is acting like a dictator. Our wedding is 3 months out and she’s asking me to whiten my teeth, cut my hair -it’s like down to my shoulders, but she wants me to look like a preppy dude I guess, and she even asked me to drop some weight. She gets super mad when I tell her to stop telling me what to do. Is this shit normal stuff to be asking someone before a wedding?
