Cast members Christopher Briney, Gavin Casalegno and Lola Tung of “The Summer I Turned Pretty” continued their promotional tour for the third season, styling looks by John Galliano for Dior, Dolce & Gabbana and more for their appearance on “The Tonight Show Starring Jimmy Fallon” on Tuesday in New York City.

Tung wore a John Galliano for Dior corset dress from a 2001 collection, along with a pair of 2013 Dior mary jane pumps. Tung accessorized her attire with Panconesi earrings.

Briney wore a suited look courtesy of Dolce & Gabbana. The look included a black blazer with coordinated shirt, beige tapered trousers and black patent leather shoes by the Italian luxury fashion house. Briney’s look was styled by Daniela Romero.

Casalegno also wore a suit by Dolce & Gabbana. The mocha brown suit featured a coordinated, monochrome aesthetic with a jacket, trousers and collared shirt with buttons running down the front placket. He also wore black patent leather shoes by Giuseppe Zanotti.

The TV series adaptation of “The Summer I Turned Pretty” has grown in popularity since its debut in 2022, leading the show to partnerships in the fashion and accessories spaces. Last June, New York City-based jewelry brand Catbird collaborated with the series on a collection of jewelry inspired by the romantic young adult show.

The collection took inspiration from young love, coastal nostalgia and a journey of self-discovery, mirroring the themes of the series. The Catbird x “The Summer I Turned Pretty” collection included delicate, feminine necklaces, rings and charms.

“The Summer I Turned Pretty” is a coming-of-age story that follows Belly, played by Tung, who finds herself caught in a love triangle between brothers Conrad and Jeremiah, played by Briney and Casalegno respectively. The latest season, based on the young adult novels by Jenny Han, debuts on Prime Video on Wednesday.
