Jennifer Lawrence is sporting an updo that uses braids for the focal point here at Comic-Con International: San Diego 2013 – Day 3 – "X-Men: Days of Future Past" Press Conference.
Medium size braids are started near the face and brought around to the back to a knot at the back of the head. They are placed randomly so as not to seem too planned. This lends to an element of fun and spur of the moment.
