How intriguing! Contrary to wikipedia's entry for "chenille," which suggests "in the 1930s, usage for the tufted fabric became widely desirable for throws, mats, bedspreads, and carpets, but not as yet, apparel," here are some images which suggest that chenille garments seem to have been rather popular, for bed, the beach, and possibly beyond, in the 30s and 40s?
