Sister, sister, sister act!

While older sister Kim Kardashian made a statement in a glitzy robe by Jean Paul Gaultier at the 57th Annual Grammy Awards, Kendall Jenner, Khloe Kardashian, and Kylie Jenner were spotted in flashy ensembles at the GQ and Giorgio Armani Grammys Afterparty (sponsored by Patron Tequila) in Hollywood on Sunday, Feb. 8.

Carrying on one of the night's biggest style trends, Kardashian, 30, modeled a black Constantina & Louise dress dripping with beaded details—a trend also spotted on Nicki Minaj, Jessie J, and Beyonce's frocks. The Dash co-owner's dress also boasted a plunging neckline and a thigh-high slit. A L'Dezen by Payal Shah ring, slicked-back tresses, and a red statement lip completed the look.

Likewise, Kendall, 19, flaunted her assets in a semi-sheer lace dress with a plunging neckline. The Estee Lauder spokeswoman also worked glam bedhead and a smoky eye.

However, Kylie, 17, perhaps went the boldest of all in a nude illusion dress with an open back and a large cutout on each hip. Embellished stripes were strategically designed to avoid a wardrobe malfunction, though the sheer dress did reveal underboob. The PacSun designer also put her signature plump pout, glossed in nude, on display.

While Kardashian and Kylie's on-and-off beaus, French Montana and Tyga, respectively, were both present at the event, a source tells Us Weekly that the ladies kept to themselves and chatted with each other at the bar—except, of course, for when they stopped to take selfies.

"So you think you can pose?!!!" Kardashian captioned one in a series of photos that she took with her sisters and posted to Instagram later that night.
