Kate Middleton's white trouser suit - 7 lookalikes we've found that are a whole lot cheaper

Kate Middleton confirms it - a white suit is your new summer essential

On Wednesday, Kate Middleton stepped out in London looking stunning in a white Alexander McQueen trouser suit - a two-piece that’s quickly becoming the style of the season. Just months earlier, Meghan Markle looked equally chic in a white Valentino suit at the 2022 Invictus Games.

Both royal ladies chose suits with wide-leg silhouettes, pairing them with white heels and matching white handbags. Besides a wedding (unless you’re the bride!) it’s a look that will evoke effortless style for any occasion and the light hue is perfect for the summer months.

While Kate and Meghan chose designer pieces, there are plenty of lookalikes on the high street in cool and flattering cuts so you can wear the look for much less. You could also dress them down with trainers or chunky sandals for a more understated look.
