"Showing Out (Get Fresh at the Weekend)" is the debut single released by sister duo Mel and Kim in 1986.

The single's B-side, "System", was originally intended to be the duo's debut release, but after getting to know the sisters, Pete Waterman felt that the song was too soft for their personalities, and halted the single's pressing. Mike Stock then wrote "Showing Out (Get Fresh at the Weekend)" for the duo, influenced by the Chicago garage house sound.

The single peaked at #3 in the UK in November 1986, and was certified silver by the British Phonographic Industry for sales exceeding 250,000 copies. "Showing Out (Get Fresh at the Weekend)" reached #1 in Germany, the Netherlands, Switzerland, and Belgium.
