Too fearful of PETA’s wrath (and spray paint) to wrap yourself in endangered shatoosh shawls or mink stoles? This season’s innocuous duvet coat can keep you equally snug. Jean-Paul Gaultier and Martin Margiela have both created parkas that look remarkably like goose-feather comforters with armholes. Margiela’s king-size version ($1,195; available at Barneys and Bergdorf Goodman) can be accessorized with duvet covers ($400-$450) that include traditional brown wool flannel for the office, plastic PVC for rain, and a floral-patterned sheet for dressier affairs. On a limited budget? You’ll just have to wait for Macy’s white sale.
