Mom Issues

My fiancé and I have been engaged for a week. Already my mother is trying to take over planning! She doesn't seem to care that my man and I are in job limbo currently and aren't able to pick a date yet or start any big planning. Yesterday she threw a fit because she wanted to pick out my MOH/bridesmaid dresses and I told her that my MOH (my best friend) and I picked them out a while ago for fun, as well as what colors I want. Not only is she also trying to make the guest list for us, Mom has also started dictating what I can and cannot wear the day of the wedding. I'm getting frustrated and she doesn't care. My man isn't happy about it either.
