The entire FROW was wearing this necklace at London Fashion Week

There are certain accessories that stand out every London Fashion Week, be that a Rejina Pyo box bag or last season's Balenciaga sock boots or trainers (Balenciaga everything really).

This LFW has drawn to a close, and what it's taught me is that micro bags are here to stay, as are cowboy boots - yeehaw - and 70s sunglasses.

As for jewellery, although shells are still a massive hit, there has been one standout necklace I've seen several times a day, every day.

There was one show on day 4 of LFW, I think it might have been Palmer Harding, where virtually one out of three editors were wearing it on the FROW opposite me.

I'm referring to the now cult Celine initial necklace. Sure, it's not from the latest season, however the fact that it's now a staple amongst the fashion set - even for fashion week where wearing new pieces is a given - is kind of a big deal.

So if you weren't sure before, now is definitely the time to jump on the bandwagon. The gold-plated, bamboo-textured alphabet pendants come in two sizes, a mini and a large, though the oversized has everyone's vote so far.

At £125 for the mini and £245 for the large, it might not be your most frugal purchase, but not only is it personal (wear your initial or your beloved's), but it's SO versatile. Wear it with a shell choker over a slip dress in summer, and over a black roll-neck in winter.

Now comes the slightly bad news, as the pendants are sold out online (here's a similar version here), however, seeing as they've been so popular, I wouldn't be surprised if they re-stocked soon.

You can also buy them in store at Celine.

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.
