Calvin Harris might have been the one performing at MGM Grand's nightclub in Las Vegas, but Taylor Swift [1] was dressed to take the stage. The singer stepped out to support her beau [2] at his DJ gig wearing a metallic miniskirt and cutout crop top. The Aqua combination would've caught our eye from miles away, being just as flashy as one of Taylor's own tour costumes [3]. Even so, Swift played up the sparkle, completing her outfit with silver rings and a gold chain-strap Jimmy Choo bag.

Taylor stood tall on platform pumps, assumingly for a good view of Calvin's show [4] — or, you know, just to turn heads. After all, Taylor's been known to tweak her look ever so slightly based on who she's dating [5], and her Calvin phase is quite striking and sexy.
