The best rooms to get ready in are large enough for all your friends, hair and makeup artists, family members and photographers. Your makeup artist and I will agree that lots of great natural light is crucial!
Designate someone to declutter about 30 minutes before I'm set to arrive.
Before I get there collect all the details that are important to you and put them in one room (dress, shoes, jewelry, etc.). Same for the guys! Get your dress out of the bag and leave out a nice hanger if you have one. No need to style them, just have them ready so I can jump into action!
Wait until I get there to get dressed or give each other notes or gifts. Guys should shower about a half hour before I arrive. Hair and makeup can be schedule busters so allow 50% more time than you originally anticipated.
