hi! there have been a few discussion on related topics here; I've found a few that may be of interest until someone comes along with additional info:

uniforms:

• Why exactly did the Nazi uniforms have such a striking style?

• Why does the Nazi-German esthetics look so evil?

• Why did the East German military retain uniforms that looked so similar to those of the Third Reich?

architecture & other:

• Did the nazis admire the Roman empire?

• Art and Fascism in WW2: Where are the Nazi novels?
