In the second half of the 20th century, the Japanese economy boomed, and silk became cheaper, making it possible for the average family to afford silk kimono. The kimono retail industry had developed an elaborate codification of rules for kimono-wearing, with types of kimono, levels of formality, and rules on seasonality, which intensified after the war; there had previously been rules about kimono-wearing, but these were not rigidly codified and varied by region and class. Formalisation sought perfection, with no creases or uneveness in the kimono, and an increasingly tubular figure was promoted as the ideal for women in kimono. The kimono-retail industry also promoted a sharp distinction between Japanese and Western clothes; for instance, wearing Western shoes with Japanese clothing (while common in the Taishō period) was codified as improper; these rules on proper dressing are often described in Japanese using the English phrase "Time, Place, and Occasion" (TPO). As neither Japanese men or women commonly wore kimono, having grown up under wartime auspices, commercial schools were set up to teach women how to don kimono. Men in this period rarely wore kimono, and menswear thus escaped most of the formalisation.).
