Curly girls (or those who can wield a curling iron like a pro) can get a classic, old Hollywood look with a messy bun at the nape of the neck and a deep side part. A few loose strands give it extra glamour.
A French twist will channel Grace Kelly classic at a holiday soirée. If you're not as daring as Gwen, feel free to lay off the dramatic volume. Just pull hair into a ponytail, twist, and hold with bobby pins.
Two great things about braids: they look like you put a lot of time into them, and the messier they get, the better you look. Starting at a side part, make a French braid along the crown, or cut yourself some slack and pop into a braid bar.
