Braid pony tail - tried this and love it! Great way to glam up a boring ponytail. My hair is super thick though so I might try to make the ponytail in the back more sleek looking by straightening my hair.
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!
