The Modular T-Shirt
Two garments in one — the essential reinvented
The first basic of our modular wardrobe, the Quantième modular t-shirt redefines the essential. Built to last, it stands apart through its versatility: a hidden button system allows modular long sleeves to be attached, offering two possibilities in a single garment. Its unisex cut, deliberately relaxed and structured, adapts to every wardrobe. Whether you choose the purity of natural white or the depth of a hand-dyed botanical indigo, this piece embodies conscious craftsmanship, made with care in Belgium.
*For the indigo version: Already shaped, this piece is just waiting for its color. We dye it specially for you on demand, a delicate process that requires 5 to 10 business days between revealing the shade and drying.
