Her clothing line later branched out to include cosmetics, underwear, eyewear, and accessories that are sold in countries such as Asia, Europe, and the United States.
Michiko produced bomber jackets for Boys Own, the seminal Balearic / Acid House fanzine, (which include original members Andrew Weatherall & Terry Farley, both known for extensive remix & production careers, DJing, record labels, etc., who started their DJing careers in Shoom) who were friends of Johny Rocca from Slough / Windsor, the UK manager for Koshino at the time.
At London Fashion Week 1987, she wore an inflatable black nylon dress, which received an originality compliment from the then prime minister Margaret Thatcher.
