Every July, executives in tech, media, and finance flock to the small resort town of Sun Valley, Idaho, for the Allen & Co. Sun Valley Forum — aka "summer camp for billionaires."

Attendees usually adhere to a simple dress code of T-shirts, vests, and athleisure for conference sessions in between the rounds of golf, schmoozing, and dealmaking.

This year, the sartorial choices were bolder than usual.

Among the usual muted grays and blues, several attendees were sporting splashes of red. While wearable health-tracking devices like Apple Watches and Oura rings are standard fare for the tech class, this year, some opted for flashier accessories: gold-chain bracelets, big earrings, and bright glasses.

The first rule of billionaire style — nothing beats a simple T-shirt.

While T-shirts in tech are nothing new, they have gotten an upgrade.

T-shirts, such as the one worn by OpenAI CEO Sam Altman, are now heavier and more fitted, in contrast to the $20 Hanes worn by coders in their college days.

"Now it's thick enough, durable, and quality enough that it's the outer layer," Victoria Hitchcock, a San Francisco Bay Area fashion and lifestyle brander, told Business Insider.

Stacey Bendet Eisner, the CEO of the Alice + Olivia fashion brand, routinely has some of the most eye-catching outfits at Sun Valley.

"Do you think that Mark Zuckerberg gets his makeup done on his way to Sun Valley at 4:30 in the morning, too?" she pondered in a video posted to Instagram.

The political analyst Van Jones arrived in a red sweater — a splash of brightness among the more muted tones typical for the event. The inspiration comes straight from the runway, Hitchcock said, pointing to recent collections from Marni and Valentino.

When it comes to the Sun Valley Conference, there's no shame in sporting branded merch. Many attendees could be seen in red Allen & Company zip-ups or carrying them in case it got chilly.

Hitchcock said "you can't go wrong" when choosing the branded gear. "These are the same people who were wearing the logos of their own companies forever and ever."

The fashion designer Diane Von Furstenberg was among a handful of attendees wearing gold-chain jewelry — a trend that Mark Zuckerberg has also recently adopted.

"You see it everywhere — that layered, chunky gold," Hitchcock said.

Others opted for colored glasses.

Fashion rules don't discriminate. Regular people and media moguls alike only have three months to wear white. So Sun Valley is a prime time for attendees to don their best colorless looks — like the Phoebe Philo outfit worn by Oprah.

In mixed knits, Lauren Sánchez eschewed typical tech style.

Sánchez, Jeff Bezos' fiancée, wore a quilted miniskirt for the conference and paired it with sneakers for a more informal look.

Bezos himself kept it classic Sun Valley in a T-shirt and vest. Despite some snazzier recent looks from Bezos, his conference outfit shows you can take the tech bro out of the basement — but you can't take the basement out of the tech bro.
