Ecchu fundoshi made by the said company had been sold by the name "Classic Pants" since before Mitsukoshi was said to have named them so, and in those days the name "Classic Pants" had already been printed on the wrapping paper, and therefore, there remains question about the opinion that "Classic Pants" is a name which "Mitsukoshi" gave.
同社製の越中褌は三越が「クラシックパンツ」と命名したと言われる以前から同名で販売しており、その頃既に包装紙に「クラシックパンツ」と記載されていることから、「クラシックパンツ」の名称が「三越」で命名されたとの説には疑問が残る。
