Royal style: Kate Middleton's 19 best hair moments

Ever the stylish royal, Kate Middleton's hair has been making headlines since before she tied the knot with Prince William. In recent years, however, the elegant royal has repeatedly shunned her signature blowout in favor of a sophisticated updo. Kate has previously walked red carpets and attended events in braided buns and low chignons.
