Bridal Party

The timeline I have in my wedding planner says to plan showers, bachelorette parties and bridal luncheon two to four months before wedding. That is just planning it, doesn`t mention having it.
I would say about a month before the wedding, to giver the bride a chance to relax and to also give her time to get thank-you cards written before the big day, that way she won`t have so much to do after teh wedding.
