Hedi Slimane’s debut Celine show may have been divisive, but there are few designers that make tailoring so desirable. Scrap evening dresses in favour of a tuxedo, a chic, nonchalant alternative, and a look favoured not only by Slimane, but also Giambattista Valli who went for crisp white and at Givenchy in the form of tuxedo dresses – a style already worn by the Duchess of Sussex. Alexander McQueen created a keyhole tux to reveal a hint of skin and Hermès showcased versions with missing buttons.
