Oh no, the dreaded chin strap…Absolutely guaranteed to make any man look like a fool. We see von Blomberg, Goering (obscured), Frank, Mussolini, Paul Schmidt, Ciano and Karl Brandt all wisely eschewing the chin strap. 

I guess nobody but Eva had the gall to inform the Fuehrer that the chin strap was a definite fashion no-no.

Weissepup: Brandt alert!! :)
