For the girls @ the wedding - French braid bun. My daughter taught me the best way to do this is to lay on your stomach on a bed and hang over the edge. Tip: braid past the French braid and be sure to rubber band the end before putting in the messy bun!
If you know how to french braid, you're golden! French braid one side into the middle and secure it with bobby pins. Then french braid the other side until it meets with the side already pinned, and pin them together!
