Unsurprisingly, makers of the iconic Kelly and Birkin bags, Hermes, ranked high on the list, too.

Debrett’s Style and Image adviser, Ines da Silva, says:

“Hermès is the one brand which if you’re not careful, can really show you up. Amazingly, some people pronounce it exactly as it’s written which is a real ‘no no’, but there’s a further subtlety to the word too. Even if you break the word in two, as you should do, it should finish with an ‘ess’ sound and not a soft ‘ez’. This is something that a lot of people in Anglo-Saxon countries are not aware of.”

Eccentric Italian label, Moschino, ranked second, with many people saying the ‘sc’ as a soft sound, when in fact it should be ‘mos-key-no.’

Savile row tailors, Gieves and Hawkes was often incorrectly called ‘jeeves’ as opposed to the correct hard ‘g’ sound of ‘Geeves.’

Perhaps most unexpected name on the list is American sportswear designer, Ralph Lauren, whose surname is often believed to be ‘lo-REN’ when in fact is, like the woman’s name, ‘LAUR-en.’

Italian brand Versace, famously mispronounced as ‘Ver-sase’ by aspiring-star, Nomi in Showgirls (1995) is in fact, ‘Vur-sah-tcheh.’

So, you might walk the fashion walk but if you want to talk the fashion talk, be sure to consult this list first:
