From Kaia Gerber to the Hadid sisters, the coolest off-duty model looks from fashion month

It's not just the celebrities and street style stars who serve up new season outfit inspiration during fashion month. The hard-working models also deserve more than just an honourable mention.

When they're not pounding the catwalk, the likes of Kaia Gerber, Kendall Jenner, Gigi and Bella Hadid continue to show us how to work the latest trends.

During New York Fashion Week Gigi schooled us in how to rock the latest 'it' item: a '70s boilersuit.

The dazzling metallic pink number by Ralph Lauren not only caught everyone's attention, but also proved to be a worthy day-to-night number.

Gigi's younger sister, Bella, has opted for full-on '90s vibes for the duration of fashion month. From vintage Christian Dior to a fluffy £18 crop top from ASOS, mini handbags and chunky trainers, you name it, she's worn it.

Naturally, she finished off the majority of her looks with a pair of tinted, diamante encrusted sunglasses, too.

Newcomer Kaia Gerber has chosen to stick to the classic all-black model uniform, or jeans and a tee, but she always manages to add her own edgy twist.

And Kendall Jenner, who made her runway return for Burberry at London Fashion Week, is now continuing to storm the catwalks in Milan and Paris.

In between her busy schedule she's kept things simple, opting for comfy trousers or Kardashian-approved cycling shorts. Her staple piece this season, though, is one that we can all get involved with: a plain white vest.
