In a new montage of home video clips, the 19-year-old -- who snagged eight Grammy nods Wednesday -- is all smiles while frolicking on a beach in a black two-piece suit.
Swift also shows off her dance moves and rides a jet ski in the nearly two-minute clip.
Her beachside style is different than her typical look.
"It's girly," the singer tells the December issue of InStyle of her fashion sense. "I love dresses, I love skirts, headbands, old antique necklaces. I'm really inspired by retro fashions and things that were beautiful then and can still be beautiful now in a more modernized way."
