'Tis the season for sitting by the fire, sleeping in and nursing hangovers. Hopefully, you'll log some serious lounge time over the holidays and should you want to upgrade your around-the-house wardrobe, just know you're not alone. Apparently proper pajamas are enjoying something of a comeback, according to retailers. Maybe it's because guys are looking to previous generations for tips to step up their sartorial game. Or maybe the pieces themselves are now cut from new materials, in a more modern fit. L.L.
