Oh, Taylor. We remember when you were a sweet sixteen country singer, with mermaid hair and a weakness for spangly cowboy boots. More Disney princess than diehard fashionista, Swift's fashion choices of old made the style set shudder - blonde ringlets, Prom Queen ball gowns and all.
Fast forward a decade - and skim over her frothy fairytale numbers and pin-up 50s phase - and Swift has switched from girly goodie two shoes to fashion elite. She's just topped Maxim's Hot 100 list (following in the footsteps of Candice Swanepoel and Rosie Huntington-Whiteley) and dropped her curls just like she dropped Harry Styles (or he dropped her - the jury's still out), debuting a sexy shag lob for the release of 1989. She's more likely to be found rocking a thigh-grazing mini-dress or cut-out jumpsuit than saccharine spaghetti straps - though her obsession with sparkle has obviously endured.

Whether you put it down to the influence of her new besties Karlie, Kendall, Martha and Lily, her hangs with Kanye or new boyfriend Calvin Harris, Swift's revolutionised her look. Sure, she may not be at the cutting edge of style, but she's not afraid to make daring red carpet choices (that Mary Katrantzou jumpsuit is a case in point). Here, we chart her fashion transformation - and the famous friends she's picked up along the way.
And because the only thing to rival Swift's changing fashion choices is her taste in men, we've delved into the archives to present her dating history from past to present. From pretty boys Harry Styles and Twilight's Taylor Lautner to older men like John Mayer (really, Taylor?) and Jake Gyllenhaal (that's better), her boyfriends have evolved in step with her style. As for new crush Calvin Harris? They make a pretty perfect match.
