Little Miss Sunshine is looking more like Little Miss Stunning these days. Former child star Abigail Breslin, who was 10 years old when she garnered an Oscar nod for her role in the 2006 Sundance hit as a beauty pageant-obsessed little girl, showed off a startlingly mature and sophisticated style at the March 5 premiere of her new movie, The Call, a psychological thriller costarring Halle Berry.

Now 16, Breslin wore her long, wavy blonde hair fashionably swept to the side and chose a super-chic all-black outfit by Alice + Olivia for the occasion: a cropped turtleneck with oversized bow at the neck paired with high-waisted, wide-leg pants. A swipe of red lipstick completed the glamorous look.

The actress has come a long way in the style department. At the 2007 Oscars, with her long brown hair pulled into a youthful ponytail, she delighted fans by wearing an age-appropriate, pink, princess-y gown with floral appliques.
