Tribal Brand-Print Stretch-jersey Tracksuit Trousers

Experimental designs are at the heart of Marine Serre's brand philosophy – and all with a pinch of signature style. For her AW21 collection titled "Core", the French designer drops a simple piece of athleisure – the Tribal tracksuit trousers – but this time it's accented with a beaded, detachable keyring at the waistband. Pull this wide, relaxed-fit pair on with a style with the brand's matching hoody we reckon.

• 92% viscose, 8% elastane

Marine Serre’s critically-acclaimed collections have a cult following. A completely new, radically independent brand, with a hybrid mixture of classic French couture shapes, sportswear references and fabrics, the brand pioneers the production of new garments based on end-of-life materials.
