Oh, what a night for Alicia Keys!

The stylish star stepped out at the 2013 Aria Awards in Sydney last night and changed not one, not two, but three different times over the course of the evening.

It's safe to say that this fashionista likes to mix it up as much as possible!

While each dress had a slightly different vibe, they all featured a similar sleek column silhouette that accentuated her curves in all of the right places.

First, she rocked the red carpet in a cheerful yellow Stella McCartney design featuring sheer mesh side cutouts, a high neckline, chunky statement necklace and bold metallic belt.

If this gown looks familiar, it's probably because you may recall the star wearing a cocktail version of the same design in emerald green at the 2012 MTV European Music Awards. Plenty of other celebs, including Gwyneth Paltrow, Brooklyn Decker and Michelle Dockery, have worn the black version of this popular designer look at previous events.

Next, the star took the stage to present an award in an elegant cocktail dress by Toni Maticevski featuring a sculptural skirt detail at the waist and knee-length hemline. Dazzling gemstone drop earrings and classic black pumps by Giuseppe Zanotti.

Can't go wrong with a figure-flattering LBD!

And finally, the talented artist wowed the crowed in a printed two-piece ensemble by Manning Cartell for an edgy downtown look that showed off a more eccentric sense of style, but still embraced her shape.

What did you think of Alicia's numerous outfit changes?
