Is it really still February? Take a glance out the window right now, and the glorious sun (this writer actually got burnt earlier) would suggest not. Spring has arrived early in London, and we’re going to be (foolishly) optimistic in saying that it’s here to stay (eek).

Though this kind of weather does have a habit of sparking uncontested joy, it also triggers one, very niggling anxiety: what the hell does one wear? Too nippy for shorts and tees, too hot for coats, it’s a sartorial minefield to say the least.

Fortunately for you (and for us) the answers aren’t that hard to find, because our Spring/Summer 2019 trend report is here to serve up some serious inspiration. Granted, we’re dipping in a tad earlier than anticipated, but hey, why would you/we complain about embracing lighter clothing?

So with our accompanying list of the best products to buy, here are the most important trends you should be embracing in the season ahead.

1. A return to elegance

Tailoring was back – and back in a big way – in London, Milan and Paris. Sure, there were plenty of beautiful suits at the usual suspects (Canali, Corneliani, Ermenegildo Zegna), but even the more outré brands dabbled in tailoring. The entire Comme des Garçons show was an avant garde musing on the suit, Charles Jeffrey Loverboy showed several tailored two-pieces and even the king of streetwear, Virgil Abloh, threw in a suit or two into his inaugural collection for Louis Vuitton. The most elegant of all the collections, however, was Kim Jones’ couture-inspired outing for Dior. You’ll never look at a double-breasted blazer (more on that later) in the same way again.

2. You need some short shorts

GQ Fashion Director Luke Day has long been a proponent of ultra-short shorts, and for Spring/Summer 2019 his time has come. Tiny bum-skimmers were all over the runways this season, with the best found in neoprene at Prada, tie-dye leather at Louis Vuitton and swirly-whirly retro print at Dries Van Noten. Invest in some now, stop skipping leg day and you’ll be ready to go by spring.

3. Suits worn with bare chests (it’s a thing)

Now you’ve got your suit sorted, you need to figure out how to wear it. Luckily, your friendly local style shrink is here to help. For Spring/Summer 2019, you should be wearing your suit with absolutely nothing underneath. That’s right: nothing. The trend was everywhere at the shows, from the baby-blue two-piece worn with naught but a bare chest at Ermenegildo Zegna to the ultra-chic stone-hued suit shown sans shirt at Hermès. If you’re going to try the trend yourself, be sure to invest in some super-strong, mark-free deodorant first..

4. Sage is the colour

There were several colour trends going on at the shows – fluoro lime being one of them – but sage was easily the most wearable shade doing the rounds. From a beautiful sage two-piece suit at Canali to a smashing sage mac at Corneliani and a series of sporty pieces in sludgy sage at Dsquared2 – you heard it here first, sage is the shade of (next) season.

5. Invest in some hiking sandals

There wasn’t a show that didn’t feature a pair of sandals in one iteration or another. The most desirable came in the form of souped-up tech walking sandals. From the heavy-duty hikers at MSGM to the nylon-webbing strap styles at Fendi.
