The garment has been specially designed so that it can be cleaned under the shower head with no soaking, dry cleaning - or even soap.
Australian Wool Innovation says it has already received 170,000 orders from Japan for its revolutionary shower suit.
AWI spokesman Stephen Feighan told The Australian newspaper that the suit could be worn in the shower, although it was probably better to drape it on a clothes hanger to wash it.
"The idea is that you hang it up and then you give it a spray, and leave it overnight, and it's dry the next morning,'' he said.
The shower suit appealed to busy corporate people, particularly those who travelled frequently or stayed up late, Mr Feighan said.
