Question

In this excerpt from Sir Gawain and the Green Knight, what does the description of the attire of the strange man say of his social status?

And in guise all of green, the gear and the man:
A coat cut close, that clung to his sides,
And a mantle to match, made with a lining
Of furs cut and fitted—the fabric was noble

The man was a peasant.
The man was a vassal.
The man belonged to the nobility.
The man was a commoner.
