Clothing is prominent in #vayeshev: Joseph's coat, Jacob's sackcloth, Tamar's mourning clothes, Joseph's garment, and others. Coverings in Scripture are often symbols of authority and protection: headcoverings, veils, mantles, robes of state, shadows, gold plating...even tree branches and pitch are used in this way.
