Oh darn, you are right.
“Boss joined the Nazi Party in 1931, two years before Hitler came to power. By the third quarter of 1932, the all-black SS uniform (to replace the SA brown shirts) was designed by SS-Oberführer Prof. Karl Diebitsch and Walter Heck (graphic designer). Hugo Boss company produced these black uniforms along with the brown SA shirts and the black-and-brown uniforms of the Hitler Youth.”
I’ve done a lot of research on Hitler and I just recently came across this info myself. Glad you brought this up. Most people don’t know that Hugo Boss was a big ‘activist’ and supporter (inc. financial) of Hitler.
