From chunky knits to tailored trousers and comfy ankle boots, this season’s must-have fashion staples have all had one thing in common: they’ve all been available in a flaming red hue. Now, though, there’s a new colours du jour taking over the high street: yup, we’re talking about that gloriously autumnal mustard yellow hue.

And, after trawling through countless Instagram hashtags, it seems as if there’s one must-have mustard drenched item in particular which everyone is obsessing over.

Say hello to Topshop’s mustard blazer.

With a flattering tailored cut and raw edge, the big buttoned blazer is a fail-safe staple for any wardrobe this autumn.

And, for those who love co-ords, you’re in luck: you can complete the ensemble with a pair of matching kick-flare trousers, too. 

With the blazer priced at a pretty reasonably £69, it has (unsurprisingly) stolen the hearts of people on Instagram:

As you can see, the blazer has been spotted everywhere, from the UK to Japan.

And, while everyone has accessorised theirs differently, they’re all equally fabulous.

The blazer is currently sold out online (and isn’t going to be restocked but is available in store), but the trousers are still available. 

However, perhaps sensing that the masses would be clamouring for more on-point mustard workwear, the high street retailer has brought out a second golden yellow blazer at £49 or a lush honey velvet number for £75. Again, the masses have descended, so it's selling out fast - but, if you're quick, there's still time to grab one before they're all gone.

So, if you fancy treating yourself, we recommend you act fast and hop to a Topshop near you.
