This research devoted to the scanning technology of improving an underwear design by means of studying male bodies morphology. Increasing demands of contemporary men about an underwear have affected the way of designing including the choosing of structure, construction, knitted materials in accordance with the body morphology, perception, possible body reshaping, etc. It requires a combination of traditional design approaches with new data base. Traditional approach used limited number of body sizes and some empirical values, but this simple data base is not fully to reflect the male bodies morphology if the fit, comfort and additional functionalities of products should be reduced. Our exploration takes into attention the opinions and demands of more than 300 young people (Chinese, Russian, Indian). The underwear they have bought most appeared the size and front crotch discomfort; moreover, the majority of respondents said, simple way of underwear sizing (such as S, M, L, XL, XXL…) doesn't give them good choice during buying underwear. So, the traditional basic body sizes for underwear design are outdated and unreasonable, it should be readjusted and reformed. We used the body scaner Vitus Smart XXL to create new data base for underwear design.
