Hilary Duff's complete style transformation

Hilary Duff first hit the big screen in 1998 as Wendy in the classic Halloween film "Casper Meets Wendy," but it was her role as Disney Channel's "Lizzie McGuire" that helped her become a household name. However, unlike many teen stars, Hilary had a pretty smooth transition into adult-life: Today, she stars in TV Land's hit show "Younger," and her personal style has matured right along with her on-screen roles.

Hilary's teenage style featured lots of flip flops, small shoulder bags, belts, bell bottom jeans and long duster sweater jackets — all of which were essentials on red carpets in the early 2000s.

Now, as a successful actress, singer and mother of two, Hilary continues to play with different silhouettes, bright colors and fun accessories. A staple of her style includes leather pants and leggings, paired with blousy tops. She's been spotted on multiple red carpets rocking the look, from an Entertainment Weekly Pre-Emmy Party to a recent edition of the Vulture Festival.

What the Hilary has made clear over the years is that she's not afraid to take style risks, either: Whether it's dying her hair or rocking a custom wedding dress for her at-home wedding to Matthew Koma, the "Come Clean" hitmaker has proven time and again that she can do it all.
