Jenna Dewan Tatum Wears Buckle Dress, Changes The LBD Game — PHOTO

The ubiquitous little black dress is a timeless staple — it will never go out of style. But even classics can use an upgrade once in a while. Jenna Dewan Tatum wore a black buckle dress for her appearance on The Tonight Show with Conan O'Brien on Monday, and the game-changing ensemble will make you view LBDs in a whole new light.

The 34-year-old donned a gorgeous curve-hugging midi dress with a plunging scoop neckline, a metallic silver clasp, and a large center cutout. But what's so special about a buckle dress, you might wonder. Well, the buckle was actually on the front rather than the back, which sort of made it look like she wearing the dress backwards. The metal piece was placed right over the her chest, flaunting a whole lot of cleavage all around. Side-boob may have made a splash in the fashion world this year, but under-boob is totally the new way to do sexy.

The actress paired the sultry piece with soft tousled locks and a bold red pout, which perfectly tied together the vampy look. The front cutouts gave the simple black dress a fresh, new feel. Soon enough, everyone will be rocking their dresses "backwards", you'll see.

Take a look at the super cool ensemble.

She totally owns it.

Dewan-Tatum is no stranger to breaking fashion rules. Let's take a look at six other times she took style risks that paid off.
