Zegna invited the fashion crowd for a sunset runway show on top of its factory in the Piedmont region, overlooking a vast natural park owned by the Zegna family and underlining the tight supply chain control at the family-run company. The collection was imbued by lightness, in shape and in materials. Forms were essential, borderline minimalist, ranging from sports suits with trousers or Bermuda shorts to tunics with inventive twists or intarsia knitwear recalling impressionist landscapes. Finer knitwear was near transparent, with hints of sheen that caught the slants of light. Bags include macramé cross-body bags.

Zegna is moving to more sustainable use of materials, deploying fabric remnants and recycled materials, while maintaining tight control of its own supply chain which runs from the animal to the fibre to the garment, and investing in new sustainable production processes. Toward that end, Zegna has pledged to plant 10,000 new trees in any city where it opens a new shop starting in 2023. Want more stories like this?
