Designer Meredith Garrett founded Signorelli in spring 2006 in Los Angeles, inspired by the secret society of the same name, a group of rebellious teenage nobility in the 1600s. Fusing comfort and character, the pieces are embellished by hand and rendered in high-quality materials—and they've drawn acclaim from a wide fan base that includes the likes of Halle Berry, Hayden Panettiere, and Kendra Wilkinson. The bonus: these tees give back, with sales from each shirt supporting one of the Signorelli Movement Foundation's eight causes, including breast cancer awareness and students in the arts.
