Another major trend for 2011 mother of the bride and groom attire is shorter lengths. There are more knee length dresses out there than ever before, many of which are so chic that a bridesmaid would be as happy to wear them as the bride's mom will be. No longer does the mother of the bride or groom need to completely conceal her figure under a long skirt and long sleeves. If the wedding is not too formal, by all means show off your great legs!
