While all ears were on Ariana Grande as she performed her new single, "One Last Time," on Jimmy Fallon's "Tonight Sho"w post-game Super Bowl special on Sunday night, we couldn't tear our eyes away from her chic black jumpsuit, and most of all, her straight-out-of-the-'90s tattoo choker.

Even though we're not sure if we're ready to accept a revival of the choker trend (*shivers at memories of 7th grade school pictures*), Ariana's head-to-toe ~lewk~ was beyond gorgeous. Her makeup and sleek high pony? Flawless. The way she accessorized her simple jumpsuit with an understatedly glittery Chanel belt and black platform heels? Beyond.

Total Sandy-at-the-end-of-"Grease" vibes, right? Could this toned-down ensemble be the end of the era of her trademark cat ears? Is she putting away her sparkly snowflake dresses for good?

Prepare yourselves, y'all—it seems like lil Ari might be stepping up her style game in a major way.
