SBO.net have traced back to find some of the kits that fans will be desperate to forget, collecting data on the ugliest kits from sources such as The Guardian and the Daily Mirror.

The research around fashion collections unlikely to make any runways was shared with Soccer Laduma.

The highlights, or rather lowlights, of the ugliest strips include the famous 1996 UEFA European Championship goalkeeper kit worn by England's David Seaman, as well as the colourful kit Mexico shot-stopper Jorge Campos had designed for the 1994 FIFA World Cup.

Manchester United, Arsenal, Chelsea and even FC Barcelona all have entries in the gallery, as researched by SBO.net.
