Mel & Kim were a British pop duo composed of sisters Melanie and Kim Appleby, active during the mid to late 1980s. They were known for their distinctive dance-pop style, heavily influenced by producers Stock Aitken Waterman. Their most notable hit, "Respectable," reached number one in the UK Singles Chart in 1987 and helped to define the upbeat, synthesizer-driven sound of the era. Despite Kim's solo career following Melanie's death in 1990, Mel & Kim's collaborative work remains significant in the history of British pop music.
