jothar:
The way the Gedolim dressed when they were bochurim is not the way they dressed when they were Gedolim.
So even though all four of these gedolim went on to dress in the same black and white and there are no accounts of these gedolim telling their talmidim not to dress in black and white, or them theirs. Nor is there any account of the gedoliim speaking out against wearing black and white today.
Yet none of this is any indication of the opinion of gedolim on wearing black and white. Is that correct?
