Looking so much greater these days, gurl!
Not only did the Problem singer show off her lengthy legs in a dangerously short sweater dress and knee-high boots, she also ditched her usual ponytail!
The outfit and hairdo totally gave the 20-year-old a more mature vibe. In fact, she was so well put together that even though her sweater's sleeves were borderline slouchy, Ariana pulled it off!!
That takes skill, which she obviously has!
