Miu Miu is a high fashion brand that was founded in 1993 by Miuccia Prada, the granddaughter of Mario Prada, the founder of the Italian luxury brand Prada. The brand was initially launched as a diffusion line of Prada, targeting a younger, more contemporary audience. The name "Miu Miu" is a nickname that Miuccia Prada was given in her childhood, and it reflects the brand's playful and feminine spirit. Miu Miu's collections are characterized by sleek silhouettes, fine material choice, and unconventional designs that challenge traditional notions of femininity. As an entity that’s become well established as a brand name without Prada’s backing, it’s safe to say Miu Miu is the most successful ‘diffusion line’ to ever exist.
