Today, we are wishing Sasha Obama, the youngest member of the presidential family, a very happy birthday! The first daughter is ringing in an important year: She turns the big 1-3. We've watched Sasha grow up alongside older sister, Malia, ever since Mom and Dad, Michelle Obama and President Barack Obama, arrived on the national political scene and we've witnessed the birthday girl transition from pretty florals to an edgier, chilled-out look (we're obsessed with her metallic lace-up oxfords!).
From her 2009 inauguration dress to her love of playful prints, Sasha Obama has come a long way since first stepping out in the public eye. Click through our gallery to see her style evolution.
