These three dresses are already winning at party season

If you are obsessed with dresses (and advent calendars for that matter), then John Lewis & Partners' 12 dresses of Christmas will sort you out for party season and beyond.

The department store has worked alongside lots of our favourite high street brands, including Jigsaw and Whistles, to create 12 bespoke dresses to cover all your festive outings, be it New Year's Eve or a Christmas lunch with your pals.

Although the idea is one dress per advent day, they are all available for sale now, because why would you wait eh? There are velvet midi dresses and tuxedos, slip dresses and silk dresses galore, as well as jazzier sequin pieces for going out out.

The collection launched yesterday, and there are already three best-selling dresses, to give you an inkling of what to invest in, should you not want to blow your budget on all twelve outfits, which would be the dream.

According to the buyers at JL&P, the dresses by Hush, Mint Velvet and Warehouse are already the most popular, and I can see why.

Penny Goldstone is the Digital Fashion Editor at Marie Claire, covering everything from catwalk trends to royal fashion and the latest high street and Instagram must-haves.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
