Have you ever had one of those moments where you stare at your closet, take a good look around, and decide you're in desperate need of a change? We've got a feeling Taylor Swift [1] has, especially after spotting her outfit at Lady Gaga [2]'s birthday party. To help the singer ring in the big 3-0, Taylor ditched her usual choice of flowy feminine skirts and dresses [3] for a piece that seemed somewhat unexpected: a black sequined jumpsuit.

Perhaps the star is on a mission to switch things up. Her recent bathing suit choices [4] were a far contrast from the high-waist options she typically rocks, and Taylor's style has seen a change [5] over the past year, ever since she started dating Calvin Harris. Whatever the reason, we love it — especially since she just gave us even more inspiration for party-appropriate attire.

Check out Taylor's new look here, then shop a sparkly jumpsuit ahead of your next big bash.

Taylor paired her jumpsuit with an ear cuff and platform heels.

It was definitely a different outfit for the star, who usually prefers fit-and-flare dresses or cutout styles.
