Naughty AND nice: Taylor Swift arrives at BBC Radio 1's Teen Awards in girly white dress... but vamps up her style in sexy hot pants on stage
Taylor Swift is the picture of a sophisticated lady, and at the Teen Awards on Sunday it was no different - when she arrived at least.
The leggy blonde stepped onto the red carpet in her signature girly style in front of hundreds of screaming teenagers at Wembley Arena.
Wearing a white vintage-looking dress, the singer wore her hair tied back and showed off her fringe as she chatted to her fans.

Vamping up her look: But it wasn't long until she went for a raunchier image in tiny hot pants while performing on stage for the audience
The short white dress did have a grown-up twist, as it featured an open back which added some extra glamour to the outfit.
Taylor teamed up the girly garment with a pair of white heels that appeared to have a kitten's face on it, and a pair of vintage-style earrings.
Her make-up consisted of her usual red lip and eye-liner look, and the 22-year-old happily obliged in autograph and photo requests from her young fans, who gathered at the red carpet to catch a glimpse of her.

But if she was trying to give off the butter wouldn't melt look, she soon switched her style when she headed out on stage.
Taylor opted to sex up her style to wow the audience as she opted for a second outfit consisting of tiny high-waisted solver hot pants.
Swift finished off the look with a sheer embellished top with her hair then worn down in curls, while she completed the image overhaul with some red lipstick.

Taylor was joined on the red carpet by fellow teen acts One Direction, Conor Maynard and Little Mix.
The show, which is aimed at teens between 12 and 17 years old's, was hosted by Nick Grimshaw.
The pretty blonde appeared on his Radio 1 breakfast show earlier this week, where she revealed her own little girl crush.
'I met Ellie Goulding last night and she's the coolest girl,' she told the DJ.
'I've been obsessed with her songs for years so I felt a bit fan girlish. I know all the words to her new song.'
