The 'Mama Do' singer has been hot on our style radar lately, so it's no surprise we can't get enough of the fancy frock she wore to The Fayre of St James in London.
Pixie ensured the waiting photographers caught her gorgeous maxi dress in all its glory by whipping off her coat as she made her way to the event.
She paired her glimmering striped number with equally dazzling metallic courts and a pretty bejewelled headband.
The pretty blonde styled her golden locks in a sleek and straight style, while opting for her signature smoky eye and nude lips combo.
Pixie performed at the festive event before continuing the night at luxury department store Fortnum & Mason, where guests tucked into nibbles and champagne.
And the songstress was accompanied by her long-term boyfriend Oliver Cheshire, who looked just as stylish (albeit a tad warmer!) in a black polo neck and grey checked blazer. Cute!
