We know who’d win a wet T-shirt contest.

Julia Fox wore a bargain white bodysuit as a swimsuit as she took a daring dip at a New York beach yesterday, wearing a sheer white style from fast fashion brand Pretty Little Thing ($20) that left little to the imagination.

The “Uncut Gems” muse, 33, tossed her newly dyed red hair in the air as she struck a pose in the cutout look, which featured a black tie at the bustline.

Fox turned the halter tie style into a bolder strapless ensemble — and also rendered it completely see-through after she went for a swim.

The former dominatrix — who recently admitted she was “permanently banned” from Bloomingdales after shoplifting as a teen — donned a pair of sporty shades and a white shell necklace along with a gold pendant and a pair of silver hoop earrings.

This is far from the first time Fox has sported a sheer ‘fit in recent months.

Whether it’s a see-through plastic poncho gown, a condom-covered top or a clear dress at the Cannes Film Festival, the actress never shies away from showing off her curves.

Her splashy look follows a busy summer of modeling gigs for the mom of one.

Fox rocked a BDSM look in ads for celebrity makeup artist Isamaya French’s latest beauty collection, and she walked the DSquared2 runway in a barely-there seashell bikini last month.

With plenty of summer days left to come, we have a feeling Fox will be gracing us with another sheer look soon enough.
