• Execs and celebs headed to the Sun Valley Conference this week, giving us a look into their style.
• The conference, known as 'summer camp for billionaires,' typically has a casual dress code.

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, though, 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.

Here's what the who's who of the business world wore at the Sun Valley conference this week.
