See fashion's highs and lows this week. Ian Gavan/GettyBest Dressed, Young Love: One DirectionTeen heartthrobs One Direction stepped up their fashion game with seriously mature style choices for the world premiere of their documentary, One Direction: This Is Us, in London. Harry Styles was a knockout in a heart-printed, black and white Burberry button-down, Zayn Malik channeled Kanye West circa—well, all the time—in a Lee Roach blazer, and Niall Horan was cool and casual in a Saint Laurent varsity jacket and pair of Nike kicks—his hair also paid homage to the frosted tips of '90s past. Donna Ward/GettyBest Dressed, Angel in White: Olivia WildeActress Olivia Wilde stopped by Late Show With David Letterman to promote her new film, Drinking Buddies, in a white, semi-sheer Theyskens’ Theory dress from the designer’s resort 2014 collection. She accessorized with a thin gold bracelet and simple Christian Louboutin sandals. Andreas Rentz/GettyBest Dressed, Midriff in the Middle: Lily CollinsAt the Berlin premiere of The Mortal Instruments: City of Bones, actress Lily Collins wore a sophisticated, minimalist ensemble. A fan of crop tops, Collins wore a Paper London sleeveless, stomach-baring shirt with a full-length Halston Heritage Resort 2014 skirt. To spice up her all-black outfit, she accessorized with an edgy, chain-like Pluma Italia necklace. Brendon Thorne/GettyBest Dressed, Sleek in Orange: Cate BlanchettCate Blanchett has been on a serious fashion kick while promoting her new flick, Blue Jasmine. For the Sydney premiere, the actress wore a short-sleeve, full-length Roksanda Ilincic gown in a light orange hue. Keith Hewitt/FilmMagicBest Dressed, Jumping for Joy: Rosie Huntington-WhiteleySupermodel Rosie Hungtington-Whiteley rocked the hard-to-pull-off jumpsuit effortlessley. Huntington-Whiteley wore a black Gerard Darel long-sleeve silk jumper, with a blue Giorgio Armani bag and black ankle-strap Michael Kors sandals as she walked around London. Plus, her light tortoise Miu Miu sunglasses made a perfect summer accessory. Jason Kempin/GettyWorst Dressed, Prom Dress Gone Bad: Francia RaisaSecret Life of the American Teenager star Francia Raisa looked like she was on her way to a high-school prom, in a very poorly selected cobalt-blue dress. Between the ponytail pouf, silver pump shoes, and the dress’s glitter detailing, the gown was way too Miss America pageant for the red carpet. Ray Tamarra/GettyWorst Dressed, Is That Bubble Wrap?: Lady GagaThe singer has toned down her look a bit, but she's still all about the eye-catching ensembles. The singer wore a wild white top and skirt combo that was seemingly a mix of neoprene and bubble wrap. Plus, her hair resembled a lion's mane. Oh Gaga, what will you think of next?
