Once the war was over and cloth rations were a thing of the past, suits reverted to the looks popular in the 20s and 30s. Lapels became wider, pants had pleats again, and no longer was the slim look in vogue. The vest was still going out of fashion as central heating became far more commonplace.
Suits in general, for the first time since their inception, weren’t the only way for men to express themselves. T-shirts, jeans, and leather jackets were a new form of rebellion. Less flashy and urban than the zoot suit these new fashions were inexpensive and accessible. But if you were a rich, educated boy who wanted to rebel than the Ivy League style was for you. Casualisation was taking the world by storm and even the Ivy League style wasn’t exempt with outfits rarely having matching trousers and jackets.
