These three coats were everywhere at fashion month, stock up now for next season

The fashion week shows are officially over, and you can always depend on the street style set to dictate the items it's worth investing in for the new season.

While a designer handbag is always a safe purchase, if you're looking for a big ticket item that'll last you a lifetime, a good quality coat is well worth saving up for in my opinion.

Over the course of the weeks in New York, London, Milan and Paris, three coats in particular kept creeping up time and time again, so if you're looking for inspiration, these are it.

It may seem counter-productive buying a winter coat when spring is around the corner, but trust me when I say you'll kick yourself if you don't have these for AW20.

it's hard to ignore the Insta-famous leather coat brand. Although it is known for its colourful coats with shearling trimmings, it also serves up some timeless classics in gorgeous brown and black leather.

Cult NY label The Frankie Shop has been a firm favourite with editors and influencers alike for years, and this season the item of choice was the vinyl coat, in either rusty brown or khaki. The oversized shape makes it a timeless item that you can wear throughout the seasons.

Say hello to your new best friend: the blanket coat. It comes courtesy of Scandi brand Rodebjer and I've lost count of the amount of times I spotted it at the shows. It's warm, stylish and incredibly comfortable, plus the oversized look gives it a luxe feel.

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.
