Your Guide to the Dress Codes at Key Events This Summer

Words by Tony Wilkes

Whether you’re an opera aficionado, a Wimbledon regular, a Formula 1 enthusiast or all of the above, the social season always promises an endless summer of events to look forward to. Almost as soon as the clocks spring forward, occasions rack up in their droves – each one with its own nuances when it comes to the dress code. Planning is key. To help you get ahead, here are the dates to have in your social calendar for 2026, from Henley Royal Regatta to the British Grand Prix – plus, the outfitting tips to make it your most stylish season yet.

“If you’re going to spend all that money, John... do the thing properly.” So said soprano Audrey Christie to her husband in 1934. Born of their shared passion for opera, the Glyndebourne Festival is now home to a world-class opera house and welcomes 150,000 people a year. Held in the grounds of the Christies’ estate in the East Sussex countryside, Glyndebourne remains synonymous with black-tie attire – co-founder John Christie felt it was a way for the audience to show respect for the performers. To introduce some personality to traditional fare, add a bright bow tie, playful cufflinks or velvet opera slippers. Or, if you’re feeling brave, swap your blazer for a Daniel Hanson smoking jacket.

The world’s oldest tennis tournament is, for many, summer’s most fashionable event. While there is no strict dress code for Wimbledon, dapper Centre Court attendees straddle the fence between a full suit and tie and something more relaxed. Smart-casual – as noted in our essential guide to men’s suits – simply means wearing components of traditional tailoring with pieces that are more laid-back. A matching linen set, for instance, worn with a T-shirt and trainers. Or, instead of a button-down, a light open polo shirt. Another useful trick is to trade your blazer for a tailored bomber jacket or overshirt in a complementary colour. Each has been tried and A-list tested by the likes of Tom Cruise, Andrew Garfield and Paul Mescal.

Since 1839, the best oarsmen from across the globe have congregated in Henley-on-Thames to compete in its prestigious rowing regatta. Now, the showcase promises 400 races over six days, and will be watched by more than 300,000 people. ‘Informal and relaxed’ reads the dress code of the Regatta Enclosure – though you won’t find any jeans or sweatsuits here. Opt for blazers, chinos and button-down shirts. In the Stewards’ Enclosure, sartorial rules are more clearly defined. Men are required to wear a suit and tie – the tradition involves a striped blazer and accompanying neck furniture – plus white or cream smart trousers. Classic Oxford or boat shoes anchor the look.

At the British Grand Prix in 2018, Lewis Hamilton compared a flat-out lap of the Silverstone racetrack to flying a fighter jet. Trackside, meanwhile, no such tricky manoeuvring is required – but there are some considerations. Guests in the Silverstone Hospitality areas are asked to follow a smart-casual dress code (much as you would at Wimbledon) – however, team merchandise is also permitted. When it comes to watches, Tag Heuer continues as Formula 1 Official Timekeeper with several motorsport models to match. Elsewhere, IWC Schaffhausen’s new release for 2026 is the George Russell Ceramic Pilot’s Chronograph in collaboration with the British driver and Grand Prix winner, in a sporty blue hue inspired by his racing helmet.

Many destinations lay claim to the moniker of ‘world yachting capital’. But, for one week every year, the title irrefutably goes to Cowes – a small seaport town on the Isle of Wight. Dating to 1826, its annual regatta attracts a unique mix of Olympic and amateur sailors, and is one of the largest of its kind globally. Dress codes vary by venue and event, though smart-casual is the general rule of thumb. Practicality is worth considering, too. Cowes can get breezy – and, come rain or shine, you’ll want to stay protected, meaning lightweight waterproofs are wise. Paul & Shark offers a great blueprint. Inspired by yachting, the brand crafts its pieces in Italy, ensuring they’re as weather-ready as they are good-looking.
