La DoubleJ is an Italian fashion and lifestyle brand founded in 2015 by J.J. Martin, an American journalist and vintage collector who moved to Milan in 2001. What began as a shoppable magazine selling Martin's personal collection of vintage jewels and clothing quickly evolved into a vibrant lifestyle brand known for its colorful vintage prints and collaborations with historic Italian producers. The brand works closely with Mantero Seta, one of Como's oldest silk manufacturers, to produce dresses, shirts, and accessories using vintage prints from their extensive archive. With the company motto "Raise your vibration," La DoubleJ embodies a philosophy of joyful maximalism that combines California's spiritual optimism with Italy's cultural refinement. All fabrics are crafted in Italy, predominantly along the scenic shores of Lake Como, ensuring the highest quality Italian craftsmanship. The brand's aesthetic reflects Martin's belief that fashion should be fun and uplifting, creating bold, print-happy pieces that make wearers feel good and spread joy to others.
