Pixie showed off her tiny waist in a figure-hugging black off-the-shoulder mini dress with a super-short, ruffled skirt, and flaunted her long, slim legs in a pair of towering white patent platform sandals on Monday (10 March).
Pixie worked an equally smouldering make-up look, with nude, Brigitte Bardot-esque lips and sexy, smoky eyes.
And we're loving her statement earrings - check the Chanel double C's!
The singer's tousled, blonde hair, worn in a simple centre parting, completed her sizzling look.
It's a far cry from the playful fluffy bra and hotpants Pixie wore for her performance at G-A-Y a few days ago.
We have to admit, while we admire PIxie's quirky sense of style, we love it when she gets glammed up.
We just wish we had a closet as big as Pixie's so we could trial as many trends in one week!
