Emily Ratajkowski models cheeky cutout swimsuit on a boat in Italy

Leave it to EmRata.

Emily Ratajkowski enjoyed a sunny boat day in Italy with friends on Thursday, dressed in an eye-popping one-piece that revealed more than it concealed.

With its crisscrossed halter top, backless silhouette, thong bottom and daring cutout, the daring swimsuit made the most of the 34-year-old model’s famous figure.

Ratajkowski accessorized with oversized black sunglasses and a Burberry bucket hat, opting for low-slung Nike athletic shorts instead of a traditional swim cover-up.

She was joined in Positano by friends and her son Sylvester, 3, whom she shares with ex-husband Sebastian Bear-McClard.

This particular swimsuit is actually one of EmRata’s more modest beach looks; last month, she posed in a one-piece from her own Inamorata line featuring a far deeper plunging front and an even skimpier thong bottom.

Shortly after, she tried to beat the tan lines by sunbathing in nothing but a baseball cap.

And in June, the “Too Much” actress celebrated her birthday with a cake inspired by her own bronzed behind — and clad in a wraparound bikini bottom modeled after one of Inamorata’s signature styles, of course.
