We expected Selena Gomez [1] to wear a few sexy dresses [2] for her appearance on Saturday Night Live [3], but when she took the stage for her first performance and the lights came on, we were totally blown away. Selena showed off a black cutout Philipp Plein design that flashed most of her midriff and her entire left leg.

The gown, pinned at the bottom of its plunging neckline and at the very top of its thigh-high slit, hugged Selena's curves, showing off her toned figure from just about every angle. And while some stars might've been hesitant to show off their dance moves in such a bold dress, Selena totally worked it. Read on to watch her belt out "Same Old Love," and once you're feeling inspired, re-create Selena's memorable look [4] for yourself!
