A Ladies Brunch for wedding guests

A friend of mine just told me about the lovely "Ladies Brunch" she attended that was given for all the ladies who attended her son's wedding. It was held the day before the wedding and all the ladies got to meet and mingle before the wedding. I have also attended a "Ladies Tea" for my niece where each guest was asked to bring an English tea cup and saucer to be given to the bride. Does anyone have a similar tradition they could share?
