The Colour is Off…
So, Jesus would have worn the same as any other man of modest means, a knee-length tunic. But would it have been white as his robes are usually depicted in artworks? In the time we are investigating, there was no method for whitening fabric. Most of the tunics worn were made from plain wool. In fact, the Bible says that His clothes only became white and shiny when He transformed into a celestial being.
Adornments
Another detail that is seen over and over in art-works depicting Christ is a blueish cape or veil draped over the robe worn by Jesus. Why it is often a shade of blue, there seems to be no explanation for its presence or its color and probably never existed, to begin with.
