The Elle Style Awards took place at the Sky Gardens in London's so-called Walkie Talkie Tower on Tuesday night - and it was a closely-fought battle for best-dressed.
But Rosie Huntington-Whiteley, Taylor Swift and a pregnant Abbey Clancy were all making a good play for the title.
Rosie HW had to be wearing the sexiest look of the night, showing off her perfect body in a leather and suede barely-there dress straight off the Anthony Vaccarello Spring/Summer 2015 runway.
The model looked incredible in the mini, which featured a pleated chiffon 'train' and a racerback style from behind, not to mention and almost-indecently short hemline.
Her hair was tousled and a bit rock chick, and we have to admit to completely crushing on this look. Rosie picked up the Model of the Year gong at the bash and it's not really hard to see why, is it?
Taylor Swift was also looking fabulous in a Julien Macdonald Autumn/Winter 2015 emerald-green dress with a vampy Madonna vibe, featuring a lace overlay and a pretty high front split.
The singer won the Woman of the Year award, which was presented to her by another winner of the night, Sam Smith.
Another fave? Abbey Clancy, who made being pregnant super-sexy in a crocheted minidress worn over a white slip, and paired with killer black patent strappy heels.
Her make up was flawless, hair was tousled, and her white clutch completed a hint of the 60s about this sartorial choice. We love.
Other stars at the bash included Ellie Goulding, Jourdan Dunn, Simon Cowell, Mollie King, Cara Delevingne, Daisy Lowe, Nick Grimshaw, Lewis Hamilton, Rebel Wilson and Olivia Wilde.
