SiiZU is a fashion brand based in New York City. Our name was inspired by the Finnish term “sisu”, a word that represents grace and strength in character, even in moments of great challenge. 

Our founding idea was based on using only the highest quality natural fabric such as silk, Tencel, cotton and linen in our clothes, all while offering designs that are fit for the everyday city lifestyle.

SiiZU hopes to bring you affordable clothes that you can connect with. Let’s stop turning a blind eye, and start to dress, better.
