‘Bigdei Lavan’ on Shabbos: An Historical Note
Regarding the Arizal’s custom of wearing white clothes on Shabbos, Rabbi Ben-Tzion Mutzafi made an interesting point:
Today this would be “Yohara”, arrogance, for most people (unless that is the local custom, like some Moshavim, perhaps), because white clothes are not as common as they once were. In the Arizal’s day, white wasn’t weird.
