"Party Girl" blends pop and funk music, with an addition of Caribbean sound to it. It was released as the second single from Inside Story, an album Grace co-wrote and co-produced, in December 1986 in Europe and 1987 in the United States. The song was remixed by Steve Thompson and Michael Barbiero for single release and another Inside Story track, "White Collar Crime", was used as the single B-side. "Party Girl" was released in a limited shaped picture disc format, that came in a cardboard stand up.

The song made little impact on music charts, however, it became a top 20 dance hit in the US.
