One day she's playing in the sand, the next she's wowing you with her knowledge of ball gowns and all things royal. My oldest (at the ripe young age of 6, mind you) is well on her way to becoming a bona fide glamour girl. Cream and gold reign supreme as her favorite colors, but let's not forget pink for all its incredible beauty. A soft, upholstered headboard with brass nails, ample pillows for added cushioning and a flat out fabulous dresser are great for now and great for later.
I'm not a fan of "kid" furniture and these choices will solidly confirm that preference. As in the rest of the home, invest in quality pieces that will stand the test of time and (hopefully) be to her liking as she grows. If not? They are lovely enough to make any guest bedroom a chic retreat for out of town visitors.
