Our We Try Before You Buy series aims to take the stress out of shopping and eliminate the number of post office visits you make each month to return failed online orders. We test new-season buys and styling ideas so you don’t have to. Here, we’re letting you know what is actually worth investing in. One common side effect of looking at all the street style pictures from 2019 is that by the end of your scrolling sesh, you’ll want at least one trouser suit. Suits have shaken off their corporate reputation, thanks to new relaxed silhouettes and fabrics that go way beyond the standard law firm–friendly navies, greys or blacks. Think sugary pinks and baby blues, not forgetting, of course, the colour of the season: green. But if you do want to wear navy, grey, black or traditional checks, there are tricks to ensure these look relaxed, rather than formal, too. It’s a super-easy outfit that requires little additional styling, making it unsurprising that it’s become a street style secret (okay, not so secret) weapon. To show how versatile—and surprisingly casual—a suit can be, the Who What Wear team have tried on dozens of suits to bring you our edit of the very best around.
