“…denim is being used as a code word for linen…”
Really? Code? Secret code? CIA? Are we talking espionage? I am at a loss. Please clarify.
“…linen is definitely not tzanua…”
How do you account for Mishlei 31:22 (It’s actually Eishet Chayil that is intuned Leyl Shabbatots) Where the meforshim appear to ascribe the coverings as linens?
