Anne Hathaway has experimented with many hair lengths, ever since shaving her head for "Les Miserables." She's rocked pixies and bobs, and lately, she's been sporting a lovely, shoulder-length 'do. It's low-maintenance yet versatile -- easy to dress up or down, and it's pretty universally flattering to boot.

Alexa Chung's shaggy hairstyle isn't exactly new -- it's kind of been her signature look for many years, in fact. Still though, it's more popular than ever right now, since undone wavy layers and messy bangs are so big.

There's no denying the fact that Gigi Hadid has the whole California girl hairstyle on serious lockdown, from her honeyed highlights to her perfect long layers and waves.

Her center-parted, slightly Jean Shripton-esque bangs are superflattering, and the length of the hair (hitting just below her shoulders) is quite versatile -- long enough to be pulled into a nice updo, and short enough to look modern and manageable.

Georgia May Jagger's '70s-esque shag is definite #goals. The blonde waves are classically gorgeous, but the piecey texture and curtain bangs keep people guessing.
