un:ten is a clothing brand where Sumiyo Ito makes each item one by one. Since 2009, she has been designing, sewing, and producing costumes, kimono clothing, toys, and art pieces, mainly through custom orders. Since 2016, she has been running an upcycling business called "Kimono Clothing," which involves dismantling kimonos and recreating them into simple Western-style clothes. She has held 9 sales events and receptions so far. In 2020, a year of global change, un:ten focuses on upcycling as much as possible for both personal and global benefit, aiming to create products that minimize material waste. The love and thoughts that un:ten puts into its clothes and people continue to flow abundantly from a spring of love.
