Battaglia sported a floral, sleeveless shift, while Dello Russo opted for a long-sleeve blue silk number with white lace and t-strap black and white booties -- all by the designer. Evan Agostini/Invision/APBest Dressed, Dressed in White: Sandra Bullock For the NYC premiere of her new film Gravity on October 1, Sandra Bullock wore a white Giambattista Valli mini-dress (featuring draping over the right arm) from the designer's Resort 2014 collection, black and white Giuseppe Zanotti heels, and Martin Katz jewels. Dennis Van Tine/Geisler-Fotopres/dpa/CorbisBest Dressed, New Look: Carey Mulligan Actress Carey Mulligan debuted her brand new brunette-do at the premiere of Inside Llewyn Davis on September 29 in NYC. Mulligan wore a black Alexander McQueen dress from the brand's Resort 2014 collection that featured a gold, jeweled halter top and slits at the waist. Pascal Le Segretain/GettyBest Dressed, Sister Act: Elle Fanning and Dakota FanningSisters Elle and Dakota Fanning sat front row at Marc Jacobs's last presentation for Louis Vuitton on Wednesday, wearing completely opposite ensembles. Younger sis Elle opted for an all-white ensemble from the brand's Resort 2014 collection paired with teal and black wedges, while Dakota wore a long-sleeve, semi-sheer lace dress (also from Resort 2014) with a black clutch. Charles Sykes/Invision/APBest Dressed, In the Nude: Cate BlanchettFor her New York Film Festival gala tribute on October 2, honoree Cate Blanchett looked effortless in (another) nude Armani Privé dress (this time custom-made of lace) and nude, pointed-toe heels. Breuel-Bild/ABB/DPA/LANDOVBest Dressed, The Classic Tuxedo: Tilda SwintonTilda Swinton always selects an androgynous look for her appearances, and her outfit for the Hamburg Film Festival was no exception. To receive the Douglas Sirk Award, Swinton sported a dark-blue suit by Haider Ackermann, which she paired with a sheer top, a diamond brooch, and black heels. To add a pop of color, Swinton wore a red-orange color on her lips. Michael Loccisano/GettyBest Dressed, Off the Shoulder: Emma WatsonEmma Watson attended the premiere of Gravity in NYC on October 1 wearing a white, off-the-shoulder dress from J. Mendel's most recent collection. Watson chose a sleek up-do and a raspberry lip to compliment the muted frock. Jacopo Raule/FilmMagic/GettyBest Dressed, Flower Power: Angie HarmonActress Angie Harmon attended the Giambattista Valli Spring/Summer 2014 show on September 30, wearing a gray silk dress featuring a subtle blue and white floral print by the designer. Marc Piasecki/FilmMagic/GettyYou Decide, Cleavage Overload: Kim KardashianRejoice! Kim Kardashian has finally been accepted by the fashion world -- and she's been killing it. While Kardashian made of slew of Paris Fashion Week appearances, her stand-out moment was the extremely cleavage-baring Givenchy dress she wore to celebrate Mademoiselle C, the documentary on Carine Roitfeld. Is post-baby Kimmy K showing off too much? Since Kardashian attended the party with new BFF, Givenchy's Riccardo Tisci, the fashion world may have been too busy to notice her lack of coverage. Stephane Cardinale/People Avenue/CorbisYou Decide, Cut it Out: Anna Dello RussoAnna Dello Russo attended the cocktail party for Carine Roitfeld's new documentary Mademoiselle C wearing a strapless, cut-out, black mini-dress by Anthony Vaccarello. Pulled straight from the designer's Spring/Summer 2014 runway, Dello Russo's choice to pair the piece with gold Tom Ford gladiator sandals gives the look a high-fashion appeal -- but then again, it's lack-of-fabric may be a bit too risqué. John Stillwell/PA Photos/LandovWorst Dressed, Oh Jesus!: Rita OraLet's pray for Rita Ora's style. A frequent flier on our worst dressed list, Rita Ora attended Unity: A Concert For Stephen Lawrence, on September 29 rocking an over-sized t-shirt featuring Mary amongst some bright flowers, a navy-blue lace skirt, and a dark denim baseball hat. She accessorized further with white pointed-toe heels and gold crucifix earrings by Dolce & Gabbana. STRDEL/AFP/GettyWorst Dressed, Structural Issues: Sonam KapoorWhat's with the pockets, Sonam? The Indian Bollywood actress attended GQ India's Men of the Year Awards ceremony on September 29 wearing a leopard print, sparkling Jean-Paul Gaultier dress from the designer's Fall 2013 Couture collection. While in theory, it works, the dress's seriously structural pockets look completely out of place.
