When you heed the call of the wild, do it with finesse. Just as the shoe-and-bag crowd has shown, exotic themes extracted from natural habitats are a snug fit for the carriage trade. All it takes is a single defining element—a hair-on-hide leopard print, perhaps—as the springboard. Move on to maple paneling in knotty, off-the-path finishes. Sprinkle in trims with a tribal taupe-cream beat. And green grows the jungle in pistachio leathers and mossy textiles.
