There is very few time left for your wedding day. Now you should choose the people you want a help, you need to inform them and share their duties.
First you need to get a list of jobs and prepare a section of work, then you should call each one of the people you want help with and ask if they are available.
Think about people who really want to be on your side, your sisters, your cousins, your best friends, think carefully about them all. Make a list for who understands better about hair styles and makeup, which one is more straightforward, which ones had better understanding about wedding dresses and fabrics.
Do not make your bride squad too croud that may creat problems with communication and coordination issues.
When you have established this squad organization, guests to deal with and solve problems such as the pleasure of the day will stay for you and you will feel more comfortable on your wedding day.
