old-fashion, old-fashioned (adj.)
Old-fashioned is the conventionally formed participial adjective, and old-fashion is a variant, made (according to the Oxford English Dictionary) of the noun fashion rather than the verb and now obsolete. Old-fashion has reappeared, however, and is criticized in much the same way and for the same reason that ice cream once was and handicap parking is now.
