The PM – or just his wife – would be wiser to borrow outfits for special occasions, as Sarah Brown and Carrie Johnnson did

Not all of us are good at clothes. Some have the gift of sartorial certainty; some suffer from a sort of “mirror blindness”, doomed to stand in our bedrooms asking “Is this right? I can’t tell,” until everyone is late for dinner. You see this even in the odd Hollywood starlet – with their PRs and dressers and favourite designers – who, rather endearingly, still can’t tell what they look like until the tabloids get together to tell them.

When your job is in the public eye, though, clothes matter. Which is why many a prime minister has reached the end of a long day of nation-defining decisions only to discover that they themselves are being defined – possibly forever – by their “too-short trousers”, which are now splashed across every tabloid front page and have their own social media account.
