Final answer:
The L-85 regulations instigated changes in men's fashion by introducing more conservative, fabric-saving styles during WWII, while significantly impacting women's fashion as well, leading to a post-war shift towards less restrictive attire.
Step-by-step explanation:
The introduction of the L-85 regulations during World War II resulted in significant changes in men's fashion. These rules limited the amount of fabric that could be used in clothing, which led to simpler, more austere styles with less embellishment. Men's suits became more utilitarian with narrower lapels, no vests, and a generally more conservative cut to conserve fabric for the war effort. However, the question asked here seems to contain a typo or miscommunication, as the L-85 regulations primarily affected women's fashion, leading to shorter skirts and simpler styles to save material for war supplies.
After the war, there was a clear shift in societal expectations and roles, particularly for women. This change was reflected in fashion, showing a move towards less restrictive and more practical attire. The changes in style that the L-85 regulations forced upon society inadvertently bolstered a growing sense of freedom and practicality in clothing, influencing fashion for years to come.
