USISI SISTER was launched in June 2019 by sisters Kathryn and Millie Allsopp. Despite almost a decade between the sisters’ ages, Kathryn and Millie found themselves buying the same accessories in different colours; and thus, the idea for USISI SISTER was born. Offering a curated capsule of modern ready-to-wear and accessories, each piece within the London-based label’s collection is offered in two distinct colourways in acknowledgment of the fact that no two shoppers are the same.
