Kim Kardashian has a fake tan to match her super-tight dress

She is known to be fond of having a spray tan.
But Kim Kardashian has seemingly gone a little too far with her latest bronzing regime.
The 31-year-old's bright orange dress was almost hard to distinguish from her deepening tan as she promoted The Kardashian Kollection at the Woodfield Mall in Schaumburg, Illinois this evening.

The attire, however, clung to Kim's curves perfectly and showed off plenty of her ample assets.
Kim paired the eye-popping outfit with some nude stilettos and an oversized bag plus a gold necklace choker.
She was joined by her sister Khloe, who opted for some questionable attire.

While the 27-year-old all-in-one patterned jumpsuit was cute, it failed to flatter her own sensational curves.
Unlike her older sister, Khloe covered up with a cropped leather jacket and showed off her huge engagement and wedding ring.

Kim was clearly in a happy mood, and it may well have something to do with her good night's sleep the night before.
The reality star was snapped snoozing by her mother Kris Jenner and the Kardashian matriarch wasted no time in posting the picture to her Twitter page.
The 56-year-old mother-of-six uploaded the snap and posted the caption: 'I love that @kimkardashian still crawls in bed with me...she's still my little girl! #favoritething.'.
