Here's a gorgeous—and dead easy—hairdo to copy, courtesy of Hilary Duff. (This is from her appearance at Good Housekeeping's 125th anniversary party the other night.)
As I keep rambling on about, hair this year is all about dry, slightly messed up textures... and I'm sure you know that braids are real big too.
How easy is this though? Just make sure your hair isn't too slick (use a texturizing product or beach spray to mess it up first), then just braid, wrap and pin.
