London-based sisters Kathryn and Millie Allsopp have combined their shared experience in design and fashion-buying to create a modern, feminine brand that eschews trends and transcends seasons. USISI means ‘Sister’ [pronounced oo-see-see] in Xhosa, one of South Africa’s eleven official languages where the sister’s mother grew up. USISI began with a simple guiding logic. Despite a decade separating Kathryn and Millie in age, each season the sisters found themselves buying the same pieces, only in different colours appealing to their different appearances. Why not, then, create a brand that offered the same classic - and ageless - tailoring they both reached for, but create every piece in two different colourways to acknowledge how no two shoppers looked the same?USISI launched its debut collection online at www.usisi.co.uk, Browns Fashion, Farfetch, and Moda Operandi in June 2019, and have expanded its wholesale partnerships for 2020.
The collection is designed in London and produced in fair trade factories around the world using all natural fabrics. At the centre of USISI DNA is a discerning woman who drives the brand’s focus to create versatile styles to carry her through the many aspects of contemporary life, all sold at an accessible price point. 

"Expect easy-to-wear transitional pieces to take you between the city to resort," says Lisa Aiken of the brand's debut collection. "The uncomplicated ready-to-wear silhouettes rendered in all-natural fabrics are effortless while the constructed bags have interesting design details like the Consti bag's swirl handle." - Who What Wear UK.
