Look statuesque in a black jumpsuit like Britney Spears

On stage, Britney Spears usually opts for super tight catsuits or sparkly dresses, so it was a lovely surprise to see her looking ultra chic in this Sergio Hudson jumpsuit for the switching on of Christmas lights in Las Vegas.

We have to admit, Britney's wardrobe is very Marmite -- you either love it or hate it. A lot of the time we question her choices, but here, we are in love. This jumpsuit makes her look tall and statuesque, something that all 5-foot 3-inch people yearn for.

Sergio Hudson, the L.A.-based fashion designer, is no stranger to dressing some of the world's most famous women. Think: Rihanna, Kendall Jenner and Nicole Scherzinger, to name a few. He loves to create super feminine, sexy shapes and jumpsuits are his forte.

Britney's features a halter-neck shape, with mesh inserts on either side. We love how Britney has accessorized it too, layering up her gold chains. Simple black shoes finish her look.

You can't buy Sergio Hudson on line at the moment, but take a look at some options we've found below.
