Clothing is not only the protection of the body, but also the aesthetic decoration of the image, but when it falls into the irrational fashion trend while pursuing aesthetics, it may bring physical oppression and chemical poison to the body, and weaken people's rational thinking ability. By combing the relevant literature, we can see that the traditional fashion criticism within the fashion industry can not effectively expose the harm of fashion clothing to the body because of its lack of independence and standards. The professional advantages of medicine can not only improve the independence of fashion criticism, but also set up a set of objective standards for fashion criticism from the aspects of criticism object, discussion method and value orientation. By intervening in fashion criticism, medicine not only plays a cultural value in guiding the rational development of fashion, but also finds an effective way to popularize professional knowledge. The reasonable collision between medicine and fashion is the active fit of the New Medicine.
