Bella Thorne has certainly grown up! The 18-year-old actress took to Instagram and Snapchat to show off an edgy denim-on-denim bikini look Sunday.

"Was feelin it with my bunny ears today :) (you can barely see them in this photo but I promise they are there) #ootd #vintage," the former Disney star captioned an Instagram post that shows her leaning against a brick wall and flashing a hint of her toned abs in a J Brand denim string bikini top and striped, high-waist jeans from Topshop.

To make her look street style-ready, the red-haired stunner draped a black leather jacket over her shoulders and finished off her ensemble with oversize sunglasses and chunky black platform boots.

Thorne continued to tease fans on Snapchat with selfie after selfie of her chic double-denim look. In one close-up shot, the actress removed her sunglasses and gave a closer look at her silver sequined choker. She opted for a simple makeup look with bold eyebrows, flushed cheeks, and a plum lip, and pulled her red tresses back into a half-up hairstyle.
