As stars continue to prep to look their best for the Hollywood's biggest night, others have already turned heads at pre-2016 Oscars parties.
Kourtney Kardashian, Alicia Silverstone, Hailee Steinfeld and Modern Family stars Sarah Hyland and Ariel Winter were among several actresses who showcased cute looks.
Kardashian, 36, was spotted leaving William Morris Endeavor's bash in Beverly Hills while sporting a low-cut black cut-out crop top, black leather shorts and a black matching blazer and pumps.
A source told E! News exclusively she attended the party with several girlfriends. She was spotted chatting with Victoria's Secret model Alessandra Ambrosio and drinking cocktails and doing tequila shots with her. Kourtney later posted on Instagram a photo of the group eating burgers.
The party was held at Paul McCartney's former home. Other attendees included Ben Affleck, who appeared rather glum, his longtime friend Matt Damon and several models.

Silverstone, 39, wore a tea-length, sparkly gray spaghetti strap dress and black sandals to the ninth annual Women In Film pre-Oscar cocktail party, co-hosted by Perrier-Jouët, in West Hollywood.
Elsewhere in town, sporting a sheer black lace bodysuit tucked into black tuxedo pants with lace cut-outs, Steinfeld, 19, co-hosted a DJ night, presented by Vanity Fair and L'Oreal Paris, which Hyland, 25, and Winter, 18, also attended. Guests received an Apple TV (worth up to $199) with their invitation, E! News has learned.

Both Modern Family stars brought their boyfriends.
Rocking a high braided pony tail, black cat eye makeup and a dark beige pant romper with heels, Hyland stayed close to beau Dominic Sherwood all night and appeared to be in great spirits. The two enjoyed several cocktails, while she was also spotted holding a glass of white wine and a Stella beer, E! News has learned. Sherwood wrapped his arm around the actress and the two kept looking into each other's eyes.
Winter, who wore a white, long sleeve, asymmetrical mini dress, attended the party with her boyfriend of more than two years, Laurent Claude Gaudette. The actress felt a little under the weather and her beau often brought her tissues. Hyland was seen telling her, "You should go home and sleep!" to which Winter replied that she had "napped for six hours already" but was still exhausted.

Joe Jonas, 26, also attended the bash with his band DNCE and was spotted chatting with Hyland and Steinfeld.
She did not drink alcohol and was seen hitting the dance floor with actresses Bailee Madison, 16, and Sabrina Carpenter, 16, E! News has learned exclusively. The trio was spotted giggling and dancing together for about 20 minutes. Steinfeld later took selfies with fans and hit the photo booth with her gal pals.
