Years before Project Runway made fashion design cool and brought the process to the mainstream (and some time before DS game developers began pumping out similar games), a Japanese studio named Watermarks Ltd. planned to create Style Laboratory, a fashion design simulation game for the original Xbox.

The title was never released, though, likely due to the Microsoft console's poor sales in Japan, and it doesn't look like the company is around anymore. As far as I know, the only game it ever put out was The Book of the Watermarks for the PS1 in Japan.

Style Laboratory was initially shown at Tokyo Game Show 2001 (in English) and enabled players to take on the role of a young fashion designer hoping to stake his or her claim in the industry, dressing up models according to season. You can see screenshots showing more of the game's models walking down the catwalk at Unseen 64.
