Emma Watson, J.K. Rowling Go Dark And Lacy For 'Harry Potter' London Premiere

Stars played it safe and experimented with lace at the world premiere of "Harry Potter and the Deathly Hallows: Part 1" earlier today in London. The event's most ubiquitous accessory? Poppies to commemorate Remembrance Day, a British holiday honoring the soldiers who died in World War I. Despite the somber reminder, reigning fashionista Emma Watson was all smiles as she ruled the carpet with costars Daniel Radcliffe and Rupert Grint.

Hermione would never dare wear this sexy dress, but Emma pulls it off with ease. On another young starlet, a lace-and-feather frock could look skanky or garish. Paired with simple black platform pumps, minimal accessories and a pixie ’do, however, this ensemble on Emma earns an A+. She also deserves accolades for her flawless makeup: softly smoked eyes, nude lips and a hint of faux tan. 10 points for Gryffindor!

Ginny Weasley wouldn’t wear Bonnie Wright’s outfit either, probably because it’s so drab. Come on, Bonnie—we know what a budding fashionista you are! You don’t always look fabulous, but we can usually count on you to make a statement, which makes this matronly look that much worse. Bonnie’s saving grace? Matching red lips and nails, which add a youthful hint of color to her shapeless dress.

Both of "Deathly Hallows"' leading men looked sharp on the red carpet. Rupert Grint went sophisticated in a dark suit paired with a matching gray shirt and tie, making him our best-dressed redhead. His shirt color (or lack thereof?) makes his ginger mane pop, as it should. Weasley is our king!

We were happy to see that DanRad decided to comb his hair for the occasion; yesterday’s photocall had us a little worried! Mr. Harry Potter caught our eye in a perfectly tailored dark suit, black shoes and simple blue tie. We hate to say it, but the "boy who lived" is officially a man.

Clémence Poésy looks like she stepped right out of the 1980s in a navy lace ankle-length dress with puffy sleeves…and that’s not a good thing. Also, is that a book she’s carrying? While the girl is undoubtedly gorgeous, this dress is better suited for my grandmother, not a twenty-something actress.

J.K. Rowling, however, shows us long, dark lace done right. Incidentally, doesn’t she match Emma kinda perfectly? They could pass for a mother-daughter pair in these gowns. Well done, J.K.

"Let Me In" star Chloe Moretz has played a superhero and a vampire, and now we know she’s a wizard fan too. The 13-year-old actress looked age and seasonally appropriate in a plaid baby doll dress with opaque tights and Mary Janes. It’s a cute, stylish look that doesn’t try to steal the spotlight.

Tom Felton may be our No. 1 "HP" hottie, but he’s definitely not our No. 1 red carpet star. His distressed brown shoes and baby blue tie don’t match his suit, and he seems to have taken the faux tan a little too far. We know you can do better, Draco!
