Even Issey Miyake, the designer, couldn't resist being in the audience to watch the MOMIX dancers perform in his clothes in the St. Bartholemew's Church auditorium last week. Miyake had seen the dancers perform in a small church in San Francisco. "They are like a laughing body, so happpy and so free," explained Miyake. So he engaged the small Washington, Conn., troupe to model his Plantation collection, his all-cotton, machine washable, less expensive line, in Japan. They were such a hit he decided to show his clothes the same way in New York, with the addition of a few models. "My Plantation collection depends so much on the people wearing the clothes; people who wear them really design them as they wear them," he said.

It was a brilliant match. The clothes are light and loose with big dresses and easy pants and oversized sweaters and shoulderbags, and the dancers are agile and witty and never restricted by the clothes. (Plantation is in Washington at La Boutique Franc,aise.)

Miyake, one of the rare designers who gives credit to his assistants, says next year he will take his name off the Plantation line entirely and use it as a showcase for young Japanese designers.
