Taylor was riding the crop top tend PLUS the newer track pants trend. It's that comfy girl look set off by sky-high heels.
NOT an easy look to pull off. You can't even grab an inch of flab on this girl! Still, Taylor makes the sexy ensemble appear elegant, classic + chic.
NO belly button showing. Always lady-like. And there was a sparkly blazer she later removed, even though it was hovering around 30 COLD degrees at Dick Clark's Rockin' Eve show in New York City!
So, will you slip into a pair of track pants in 2015 and ride the trend like Taylor?
We've hunted down a pair to give you a head-start.
