Our Sister

Our Sister is a creative studio based in the vibrant city of Antwerp, Belgium. Founded in 2018, Our Sister is the sister brand of Castart, a designer and manufacturer of responsible clothing for men.

Our Sister's designs include personal women's clothing with an interesting union of colours and textures.

Just as Castart's aim was to change the way men dress in a more playful and versatile way, Our Sister has a unique personality.

Our Sister relies on quality fabrics, durable fibres and clean details. The brand's designs help you find your own style and stand out from the crowd.

Our Sister aims to combine a young and bold team of designers with responsible and ethical European clothing production in Portugal, Romania, Scotland and other countries. The brand always strives for the best quality and comfort in its clothing.

The production process is constantly monitored and the performance and durability of ecological materials are constantly tested. It is important for Our Sister to know both the people who make their clothes and the origin of the materials.
