What do Antonio Banderas, Kendall Jenner and Prince Charleshave in common? They’ve all fallen for the charms of an all-in-one ski suit – the latter so much so that he wore the same grey jumpsuit to chase the powder every year from 1987 to 2006. (How’s that for an investment buy?) On the slopes now, Eighties colourways have a certain ironic appeal, especially if they’re the archival turquoise, fuchsia and lilac mash-ups squirrelled out from the O’Neill archives. But if you’d rather keep it classic, there’s nothing chicer than a white onesie by Moncler. Zip up and hit the slopes with Vogue’s edit of the best all-in-one ski suits to buy now.
