The 'Mama Do' singer - who is currently appearing on Strictly Come Dancing - shows off her chic sense of style by teaming her frayed jean Guess skirt with towering black courts, complete with cute gold embellishment on the toes.
She's also rocking an adorable pair of lace socks and a black shirt with gold studs running down the back, plus several stacked boho-style bangles and a striking white manicure.
And while we normally spot Pixie with her blonde locks styled in prim and proper curls, this time the stylista gave her look a rock chick edge with tousled just-got-out-of-bed waves.
In the issue, Pixie explains how her love for fashion relates to her music, saying: "If my new album were an outfit it would be a fun little sixties shift dress. It's my favourite era fashion-wise and the music was the best.
"I love the funky outfits, the colours and shapes and even the out-there Austin Powers style. I did a show at G.A.Y for my last single where I went all out dressed as a fembot from the movie. It was fun! Fashion should be fun and it's great when you have a whole identity for an album campaign."
"I'm so excited about Cosmo FashFest," she says. "My best Cosmo memory is dancing at the Cosmo awards with my friends when I won the newcomer award. Cosmo is all about fashion and friendship! I always try to take my friends to all the fashion parties I get invited to because when I'm busy it's the only way I get to see them.
"I really enjoy fashion week but it is always really rushed. There are so many shows and outfit changes and traffic... not to mention my time keeping is terrible so I've actually missed shows in the past. They normally run behind schedule so I try to bank on that!"
