Stay Stylish Above 30°C – Your Summer Outfit Guide

The summer heat is here, and with it the age-old question: what can you wear that's comfy and stylish when it's over 30°C? We've rounded up the freshest summer outfit tips so you can stay cool and stylish even in the hottest weather.

Light, breathable summer tees

Rule number one: go for natural, breathable fabrics like linen, cotton or lightweight canvas. They help prevent excessive sweating and keep you comfortable. Our range has loads of tees made from these fabrics – perfect for hot days.

Vlone, Travis Scott and Stüssy tees typically tick this box.

TIP: Pairing an oversized tee with cycling shorts or wide-leg shorts is a great shout. This combo isn't just comfy – it's seriously on trend too, so you can easily stand out from the crowd in the summer heat.

Colours and stylish combos

A well-chosen colour palette is the foundation of any summer wardrobe. This year, pastel shades, natural earth tones and classic black-and-white combos are leading the way. They don't just give you a light, fresh look – they're perfect for hot summer days too.

Why go for pastels and earth tones?

Pastels (like pale pink, mint or light blue) have a cooling effect and give any summer outfit a light, clean style. Earth tones like beige, terracotta or olive green, with their natural, warm hues, work beautifully with sunny weather, making them ideal for a relaxed yet elegant look.

Classic black and white: never goes out of style

Black and white together is a timeless, go-with-anything choice. It's not just easy to mix and match – it's practical in a summer heatwave too, as white pieces reflect the sun's rays while black adds character and elegance to the overall look.

Comfy kicks

Your choice of kicks plays a big part in your summer outfits too. Go for light, airy sneakers that stay comfortable all day and look stylish at the same time. Models like the Yeezy Slide or the Yeezy Foam Runner, for example, are perfect for days by the water and for summer streetwear style.

Accessorise in style

Don't forget your sunglasses or a cap – they don't just protect you from the blazing sun, they double as stylish accessories too.
