When Taylor Swift burst onto the music scene in 2006 at the age of 17, she was a cutesy, cowboy boot-wearing country girl. But she has made quite the style transformation, evolving into city sophisticate with countless haute couture dresses from luxury designers including Oscar de la Renta and Vera Wang.
Now, Taylor has turned 23. And to mark the birthday of the country singer, the fashion team at HELLO! Online has compiled our 23 favourite looks from the star's designer-packed wardrobe.

In her downtime, Taylor is a fan of vintage teadresses with cute patterns and quirky motif jumpers, as displayed when she took a stroll through New York's Central Park with new boyfriend Harry Styles of One Direction.
The star looked cute in her fox sweater, paired with brogues and a burgundy coat for a suitably autumnal look.
But her red carpet looks are a different matter altogether. The star usually sports her signature sequin dresses, making sure to dazzle on her nights out.
One of her standout frocks is the gold, Zuhair Murad minidress that had flashbulbs blazing at the Vantiy Fair party. And she was simply stunning in a crystal-studded Collette Dinnigan frock at the American Music Awards.

Speculation has been rife about Taylor and Harry's relationship status for several months now. The One Direction singer and the US pop superstar were first linked after they were spotted looking friendly on the US X Factor.
And they were seen strolling through the Big Apple together. Though there were no big displays of affection, it was clear the pair were getting to know each other a little better.
A minibreak away together soon followed. They could have had their pick of exotic, far-flung locations, but Taylor Swift and Harry Styles chose the picturesque little town of Bowness in the UK's Lake District as the site for their first ever holiday.
The loved-up pair caused a stir on their day out ahead of Taylor's birthday. They were spotted feeding white doves in the town square as well as sightseeing and shopping.
