An Etymological Dictionary of the German Language/Annotated/Hose
Hose, feminine, ‘hose, stocking, breeches,’ from the equivalent Middle High German hose, Old High German hosa, feminine; compare Anglo-Saxon hosu, English hose, and the equivalent Old Icelandic hosa; Gothic *hŭsô is by chance not recorded. ‘Hose’ was originally (in Old High German, Middle High German, Anglo-Saxon, and Old Icelandic) applied to a covering for the legs reaching from the thigh, or even from the knee only, and often also to stockings and gaiters. Considering the numerous correspondences in Keltic and Romance the Teutonic term is certainly original; the Teutonic words found their way into Keltic (Cornish hos, ‘ocrea’), and Romance (Old French hose). The connection of Hose with Old Slovenian košulja, feminine, ‘shirt,’ is dubious.
