There are multiple artists with this name:

1. A solo project by London-based artist and Shit Girlfriend's member Natalie Chahal. In 2017 she signed with Stockholm's PNKSLM Recordings to release her first EP, Waist Management, after touring North America. She would later release her debut LP, Keeping Up With Miss World, in 2018.

2. A side project by Jonathan Perkins, a working session and touring musician who has contributed to writing credits for Top 20 hits in the UK. He has released three albums with his MISS WORLD band, including a self-released album in 2007.

3. Described by the artist as, “demented industrial disco”, Miss World’s debut on Machine Tribe Recordings seethes with overdriven beats, primal synths, and grinding bass. Miss World Will Gas You All runs the gamut from dancefloor stompers to slow burners while never stopping to take a breath between tracks. No speaker is safe from the sonic bombardment dished out by this release. It’s said stiletto mules can concentrate 1600 pounds per square inch and that is what this sounds like. - from Bandcamp
