Our Sister

Creative studio assistant


Men’s brand Castart (2018) & female counterpart Our Sister (2021) are two emerging Belgian brands born with the idea of creating garments with heartfelt textures and vibrant colours that are well-balanced, shifting clothing into a more playful and diverse world. Since launching the CASTART first collection in 2018, we’ve always done things differently. The definitive creative thread that runs through each of our collections is one of an artistic journey which allows you to tell your story through fashion. Our Sister is the female counterpart of Castart launched in 2021. The identity between both brands will embrace each other such as the source of fabrics but so as within a family we believe in strong similarities and unique personalities to create an outstanding style for men, women and non-binairy individuals.
