Check out that cut-out detail!
The 'I Knew You Were Trouble' singer hit the red carpet for the premiere of One Chance at the Toronto International Film Festival in Canada.
The film tells the story of Britain's Got Talent winner, Paul Potts, and Taylor's song 'Sweeter Than Fiction' features in the end credits.
She opted for a simple get-up with an LWD (little white dress!), strappy heels and vintage-esque earrings.
While her outfit was minimalist, Taylor's hair certainly wasn't! From the front, it looked like a classic ponytail but when she turned around, she showed off a snazzy plait and plenty of volume.
She even switched up her fringe a little, sweeping it to one side.
Loving her look? We've spotted something pretty similar, just £40, from Topshop.
Effortlessly elegant... we like it a lot, Taylor!
