Black and blue works for steaks, bruises and fashion?

Believe it. At the Academy of Country Music Awards Sunday evening from Las Vegas, black and blue turned up as the most chic combo of the night.

Nicole Kidman started the evening's trend in a sleek deep blue snakeskin embossed sheath by L'Wren Scott with black fur trim on the shoulders.

Carrie Underwood, usually classic in ladylike frocks, took to the stage to perform in a black and beaded denim bustier mini by Nikki Lund and Richie Sambora's WTB that made her legs look like they went on forever. Once she was joined onstage by Aerosmith and "American Idol's" Steven Tyler, we quickly got why she upped her outfit's rock 'n roll quotient.

And Sugarland's Jennifer Nettles performed with her band in a super chic combo of skinny black pants, sleeveless duster jacket and a deep-V blouse in royal blue and then with Rihanna in a black and purple-ish blue jumpsuit.

It's a look that's easy to put together, yet gives you a more complex look than head-to-toe black or blue.
