Sport science progresses step by step in the world. This work is a challenge to develop the athlete woman swimming suit with low fluid drag. To begin with, the fluid drag of the woman swimming suit is very small. It is very difficult to measure the several percent difference in the fluid drag of the swimming suit. Special experimental apparatus is developed to measure the fluid drag, precisely. It can successfully measure the fluid drag of athlete woman swimming suits at the precision 1〜2%. As a result, the cloth with low fluid drag is found. It is worked water repellent into every other stripe on the cloth. The cloth is woven of thin threads (polyester 80% and polyurethane 20%). Also, the relationship between fluid drag for the model body and the water depth from the water surface to the model body is investigated in details.
