Lauren Sanchez showed off her toned midriff in a tiny crop top as she attended the Allen & Company Sun Valley conference on Wednesday with her husband, Amazon tycoon Jeff Bezos.

The invitation-only retreat, which is known as the 'billionaires' summer camp,' brings together some of the most powerful leaders from across industries, like Apple CEO Tim Cook and OpenAI’s Sam Altman.

For the past two years as Bezos has attended the weeklong retreat, Sanchez has been by his side, and it looks like this time is no different.

Sanchez was spotted hand-in-hand with Bezos at the event on Wednesday, sporting a light pink, cropped Oxford-style shirt with a tie at the bust, leaving her abs on full display.

She completed the look with a long, pink-and-black patterned skirt by Dior, which retails for $3,600.

The skirt is made from cotton poplin, and hit right at her belly button, complete with a dainty bow in the center.

To accessorize, the Fly Who Flew author appeared to carry a white Hermès Birkin 25, which is listed on resale sites like Madison Avenue Couture for over $32,000.

She tied everything together with a pair of sky-high, neutral-colored pumps, massive diamond stud earrings and black Aviator-style shades. 

Bezos, for his part, was dressed down in a black short-sleeve polo shirt, dark wash jeans and a pair of black boots.

He wore similar shades as his wife, Sanchez.

Ivanka Trump and her husband, Jared Kushner, were also seen at the conference on Wednesday.

One day prior, Sanchez and Bezos were spotted watching the USA vs Belgium World Cup match. 

Bezos wore an eye-popping red and white striped shirt, while Sanchez opted for a more toned down black T-shirt.

The pair looked a little downbeat as USA lost to Belgium 4-1 at Seattle Stadium, in the city where Amazon is headquartered. 

The big event comes just a few weeks after the couple celebrated their one year marriage anniversary.

Last June, the two hosted an extravagant, multi-day event for their nuptials in Venice, Italy, surrounded by over 200 friends and family, including A-listers like Kim Kardashian, Kris Jenner, and Ivanka Trump.

Ellie Goulding performed at their reception, while Usher also sang at their pajama-themed brunch the next day. 

The estimated $20 million, multi-day event also included a foam party on Bezos' yacht, a lavish pre-nuptial dinner and a post-wedding lunch at the iconic Harry's Bar. 

The happy couple got married in a restored amphitheater on the island, as Sanchez wore a high-neck, long sleeve lace Dolce & Gabbana gown that took over 900 hours of atelier work to make, per Vogue.

The gown featured a flared skirt, long veil, and a tight-fitting waist, with tons of buttons going up the middle.
