Why were the German WWII uniforms, architecture, film etc. so compelling re design aesthetics?

The officers still had fancy uniforms, including those shoulder boards they love, but during the Civil War, Reds would torture captured White officers by nailing them into their shoulders. Years later, after Stalin had shot all his best officers, and then had to rebuild an officer corps in a hurry, he brought back all the fancy uniforms.

Color me edumacated. My knowledge of Russian uniforms extends from the Russo-Japanese War / WWI period, but apparently skipped the revolution to head right into the mid-Stalin era.
