Carl Knotted Stretch-Jersey Top

Arming you with a wardrobe full of versatile basics (alongside its covetable trend-ticking pieces) that won’t cost the earth is Reformation’s mission. Proof? The Los Angeles-based label whips up styles like the Carl top in jersey made from eucalyptus trees, which only take half an acre to produce a whole tonne of fibre. It’s shaped simply and finished with a knot at the chest, so you can slip it on with everything from denim to flowing midi skirts.

• 88% lyocell, 12% elastane

Long before it became fashionable, Reformation made sustainability cool, with limited collections of dresses, ethically-made in LA with ‘deadstock’ material. They’re still leading change, promising to be climate positive by 2025.
