Providing your wedding party with clear direction will help you get less questions as the day approaches.  As soon as you are certain, send out information on clothing requirements, hotels, and anything else that will help them prepare. Remember that if you’re doing specific clothing, ordering and alterations take time! One of the great things about how social media works currently, is you can easily set up a group chat, or a Facebook group in order to get information to everyone in a timely fashion.
