What does backless mean?
Backless is an adjective formed by attaching the negative suffix '-less' to the word 'back', meaning simply 'having no back' or 'with an open back'. It applies most often to clothing — a backless dress, gown, or pair of heels leaves the wearer's upper or lower back exposed — and to furniture, where a backless chair, stool, or bench offers no support behind the torso. In fashion contexts the word frequently suggests glamour, daring, or formality: backless evening gowns became a signature of high style in the early twentieth century and remain a red-carpet staple. In everyday use it is entirely neutral, describing everything from kitchen barstools to garden benches. Because it is built from two transparent English elements, its meaning is immediately graspable even to new learners, making it a useful example of how '-less' compounds convey absence in English.
(Of clothing) having an open or uncovered back.
"Her backless evening gown drew admiring glances all night."
Most commonly applied to dresses, gowns, tops, and footwear.
(Of furniture) having no back or back support.
"We pulled a backless stool up to the kitchen counter."
A single suffix turns one of English's most versatile words — 'back' — into a fashion statement: backless has been turning heads since the 1930s, when daring evening gowns first bared the spine in public.

Etymology of backless
Backless is formed within English from the native word 'back' plus the suffix '-less', which derives from Old English 'lēas' meaning 'free from' or 'devoid of'. The compound follows the same pattern as countless other '-less' formations such as 'endless' and 'shameless'. The word became established as back-revealing fashions spread in the late nineteenth and early twentieth centuries.
How backless is actually used
Neutral in tone and common in fashion writing and interior design contexts. When applied to clothing it often carries a connotation of elegance or boldness, especially for formal evening wear.
