Christophe Lemaire is the go-to designer for a guy who needs a solid and structured wardrobe of daily essentials. A soft flannel shirt; black shearling jacket; Shetland tweed topcoat; high-waisted denim pants. Also, the two, both elegant and casual, pair of shoes –  polished black derbies and white moccasins. Indeed, sometimes the codes of Lemaire need an ease-up – however, if talking of the seasonless must-haves, this supremely French label is always a reliable choice.
