Lauren Sánchez’s Chanel crop top will set you back $4,450

This tiny top is worth a pretty penny.

Lauren Sánchez took a stroll with fiancé Jeff Bezos in St. Barts on Sunday during her 54th birthday weekend, clad in a casual yet pricey outfit.

The helicopter pilot showed off her abs in a cropped Chanel Formula 1 T-shirt featuring a race car and the house’s logo on the front.

While the tiny top’s not available to purchase online, it originally retailed for a whopping $4,450, as confirmed by Highsnobiety.

The sporty design was part of the French fashion brand’s F1-themed cruise 2023 collection and popped up at the Miami Grand Prix in Florida earlier this year — which Sánchez attended with Bezos, incidentally.

Patrick Mahomes’ wife, Brittany, modeled a tank top from the same coveted collection at the race.

The month was a special one for the couple, with Bezos proposing to his longtime love just a few days after the Miami event.

The St. Barts outing is part of a special birthday weekend celebration that saw the brunette beauty dancing on top of tables at La Petite Plage.

She later posted a slew of photos celebrating on Bezos’ yacht, with the birthday girl flaunting her figure in a red semi-sheer Nensi Dojaka dress and surrounded by a bevy of similarly scarlet-clad guests.

To top it off, the future Mrs. Bezos accessorized with a gold “B” necklace.

We can’t wait to see what Sánchez brings out of her closet for her actual birthday on Tuesday.
