You’ve heard of jumpers spun from wool and cotton, even alpaca, but how one whipped up from eucalyptus trees? Enter: Reformation’s Kelly jumper. Spun from lyocell made from the wood pulp of the trees (which only requires half an acre to produce a whole ton of fibre), it’s shaped with blouson sleeves and topped with a turtleneck. Slip it on with a pair of (sustainably made, of course) jeans to complete the L.A vibe.Reformation stretch knit jumperDetails:TurtleneckLong puffed sleevesRibbed trimsSlips onMade in USAFabric:96% lyocell, 4% elastaneMidweight, stretchyFine knitSize & Fit:Model is 5ft 10in / 1.78m and wears a size smallSize small: Length 17in / 43cmTrue to sizeCut to a slim fitCare:Hand wash
