No "I see London, I see France" syndrome here. The artfully-placed sheer panels on Rooney's Prabal Gurung LBD show off just enough skin, while the fluttery hemline keeps things feminine.
Rooney's avant-garde explosion of snow-colored ruffles was a perfect choice for The Girl With the Dragon Tattoo's Tokyo premiere. We like Nina Ricci's slightly more subtle take on the look, too.
High-low hemlines aren't just for Coachella, as Rooney so perfectly proves in this leather-bodice look from Michael Kors. Bold, beautiful, and not at all boho.
Dresses aren't the only items in Rooney's neutral-hued arsenal. Check out these awesomely high-waisted pinstripe trousers—paired with an architectural top and sky-high heels, they're perfect for a cocktail party or night out.
Black and white, boring? Not when there's a preppy contrast yoke involved. No wonder the girl's smiling.
If it's a daringly plunging dress you choose, forgo jewels and other extras to leave the focus on your natural assets.
Make your favorite black skinny jeans feel instantly more special—not to mention formal—with a gorgeously ruffled white jacket, like Rooney did in Tokyo.
A classic black lace number is even more memorable in an asymmetrical, one-sleeved silhouette.
If it's simple and striking you're after, nothing beats a white halter dress edged with sculptural folds.
It doesn't get more sophisticated than a black minidress with black embellishment—total tone-on-tone perfection, especially when combined with a girly sweetheart bodice.
