the.com/bathrobe

means A loose, belted robe—usually toweling or fleece—worn before and after bathing, or really any time you want clothing without the commitment.

from Simply a compound of 'bath' + 'robe,' coined once bathing became a routine domestic act rather than an occasional event. 'Robe' itself traces back through Old French to a Germanic root meaning spoils or clothing taken as plunder — so somewhere deep in its ancestry, your comfiest garment shares a root with looted war gear.
