An easy way to upgrade a simple ponytail: Curl the lengths into glamorous waves, complete with side-swept fringe that falls sexily across the forehead a la Rachel McAdams. This is sophisticated enough for an evening cocktail party, and perfect for flaunting those quietly luxe diamond stud earrings.

Get her look: Blow-dry hair with a large round brush, pulling the bangs from the part toward the ear. Curl the lengths using a medium curling iron. Pull hair into a ponytail and secure with a clear elastic.
