Etymology
the adjective 'backless' is a transparent compound formed within english from its native germanic elements. the root 'back' descends from proto-germanic bakam, which itself has uncertain proto-indo-european origins, possibly related to concepts of the spine or ridge. the suffix '-less' originates from the old english adjective 'lēas', meaning 'free from' or 'devoid of', which evolved from a noun meaning 'falsehood' or 'loss'. the logical construction is perfectly literal: 'back' (the rear part) combined with '-less' (without) directly yields the modern meaning 'without a back', specifically describing garments that expose this part of the body. this pattern of attaching '-less' to a noun to denote absence is highly productive in english.
