Popped collar worn by Duchess of Sussex and Rama Duwaji is rising in popularity, with searches at John Lewis up 1,000%

Shoppers are avidly searching for jackets that cover half your face – so much searches are up 1,000% year on year at John Lewis.

The funnel-neck jacket is boxy, generously cut and comes with a permanently popped collar, between 9cm and 14cm high running from clavicle to nose; high enough to cover your mouth, low enough to see out – just.

Dubbed the “one and done” coat by John Lewis’s design director because you don’t need a scarf, such is the reach of the style that the high-street giant (and barometer for everyday taste) currently stocks 10 different versions of it.

Elsewhere on the high street, Marks & Spencer is selling 10 of its funnel necks every day. There are suede versions in roomy shapes at Reiss, teal versions at Uniqlo, while Mango, the hugely influential Spanish brand, has been selling out of three different funnel-neck styles. Vogue magazine has just earmarked high-neck coats at Barbour, Monki and Uniqlo as its most chic. And earlier this week, the English rugby player Tatyana Heard wore a black bomber style to London fashion week.
