Borsalino, says your a true solider, as far any other name means you’re not a serious Oiveid.
How can you penny pinch when it come to the holy service of the Master of the Universe???!!
There is a Kabolah, Ish Mpi Ish, that when it says “Thou Shalt Wear a Black Hat, it means Borsalino!
Look up the Rishonim, if you cant find it there, look in the Acharonim. You’re bound to find a Tsuvah about black hats.
Especially the ones the Roshei Yeshivah wear, that points to Shamayim, as opposed to the ones the regular people wear that points the the ground, to remind us that we are not a Gadol yet.
