Kim Kardashian flashes her rear in lingerie dress that leaves little to the imagination

Kanye West better watch it -- or Kim Kardashian West is going to completely overshadow him.

Kim Kardashian totally upstaged her rapper husband on Saturday night in Miami when she stepped out in a dress that more closely resembled lingerie than an outfit for a night on the town. The 35-year-old reality star rocked an eye-popping black lingerie corset with a thong back and wore it with a sheer dress on top.

The look, which was hard to ignore, showed off a ton of cleavage as well as her famous derriere. She teamed the bedtime-ready look with a silver, diamond choker and a set of strappy sandals.

For his part, Kanye rocked an all-white ensemble, which offset his lady's look. Although the night clearly wasn't about him. Later, Kim posted a photo of her look on her Instagram account and captioned it simply, "tonight."

Kim has been rocking several seriously risque looks as of late. During New York Fashion Week she tested out a couple corset looks and also donned one sheer dress that showed off her breasts.

Clearly, Kim K. is comfortable taking some serious fashion risks lately.
