Ethical manufacturing / Social Impact
Siizu was founded by Kay Wen, Kelvin Lai and Anny Wen in 2015. Siizu’s philosophy is simple: to design and deliver beautiful, high-quality apparel made with sustainable manufacturing practices directly to customers at an affordable price point. Upon forming the brand, the team spent a year traveling and auditing factories to find the perfect partners for their brand. All of the design is done in New York by the inhouse design team. The design and pattern making team consciously utilizes the fabric to its full potential, minimizing waste.
Fabric: 100% organic and eco-friendly fabrics, 100% natural and 100% sustainably grown, 0% polyester, 0% toxins. Siizu uses merino wool from Italy, cashmere from inner Mongolian, Chinese silk from Suzhou, Japanese Tencel, and Japanese linen.
