Shanks, your thoughts about "liberty" line of clothing being something for the war effort reminded me about an odd anomaly-- women's shirts and wars-- Women skirts get shorter during times of war. During WWII, (and WWI) skirts got shorter and shorter- after the end of the war-- Dior "New Look" dictated almost ankle length skirts (1947) During the US Vietnam conflict-- Miniskirt where the rage. With extended "peace"-- women are once again wearing longer and longer skirts.
This anomaly is pretty long standing-- woman clothing get sheerer, or shorter, or deeper necklines-- in some ways more revealing than before or after the time of war.

There is a mountain of speculation as to why, one theory is, when women perceive a shortage of men, they wear more revealing clothing... the better to attract one of the few remaining men. During peace-- no shortage of men, not as much need to attract.. skirts are and clothing in general is less revealing.. (with exceptions like Jennifer Lopez)
