Hermione Granger

Even as Emma Watson has bloomed off-camera into a fashion-forward Ivy Leaguer and Lancome model, her character Hermione Granger has traversed the eight films less concerned with clothes than with keeping track of her less academically gifted pals. "I reckon she's very, very bossy," Watson joked to Entertainment Weekly. Bossy, yes, but also an increasing beautiful brainiac.

"She had a bossy sort of voice, lots of bushy brown hair, and rather large front teeth," J.K. Rowling described Hermione Granger.

12-year-old Watson returned as head-of-the-class witch Hermione, Hogwarts uniform and all.

Older and even more brilliant, Hermione got branded "an insufferable know-it-all" by one of her professors. Certainly she was smart enough to ditch her bangs for a more flattering layered cut!

A magical makeover! For the annual Yule Ball (and her date with Viktor Krum), Hermione used her wizarding skills to turn her frizzy waves into elegant spirals. As the book explained, "She confessed to Harry that she had used liberal amounts of Sleakeazy's Hair Potion on it."

In the fifth installment of the Potter series, the wavy-haired teenaged witch began to teach her skills to an army of fellow students--and upped the bickering with secret crush Ron Weasley.

Although still enrolled in her final year in school, Hermione took a rare off-campus journey in clothes of her own choosing. As this was the last movie set in Hogwarts, Watson was overjoyed to ditch her uniform at the end of filming: "I was like, 'Burn it!' Oh my God, to be done with those shoes and that uniform--that was an exciting day."

For a wedding scene, Watson looked stunning in ruffled Jenny Packham custom design. "She went from a child to a teenager, but all the time kept in mind that she was Hermione," costumer Jany Temime told Fandango. "She never asked me for more glamorous clothes, even when we were doing our cocktail dress."

In the harrowing final film, Hermione faces stiffer challenges than ever before. Watson enjoyed playing this newly-emboldened character. As she told Entertainment Weekly, "It was great fun to finally play a cut-loose version of Hermione, who's all like, 'Well, screw it! I just rode a dragon! I'm probably going to die! I might as well just kiss Ron!'"
