Final answer:
In Macbeth, the loyalty towards Macbeth from his army weakens in Act 5, Scene 2, with very few staying true. Angus uses an extended clothing metaphor to describe Macbeth's kingship as ill-fitting, likening it to a small thief overwhelmed by a giant's stolen robe.
Step-by-step explanation:
In Act 5, Scene 2 of Shakespeare's Macbeth, the loyalty of Macbeth's army is in question. The soldiers who stay loyal to Macbeth are scarce, as we see a wavering respect from the troops. Angus uses an extended clothing metaphor to depict Macbeth's ill-fitting kingship, saying in lines 24-25, 'Now does he feel his title / Hang loose about him, like a giant's robe / Upon a dwarfish thief.'
This suggests that Macbeth's authority doesn't suit him; it is as if he is a small man drowning in the oversized garment of power that was never meant for him. It conveys not only a lack of legitimacy but also implies that his power is not earned, thus it's uncomfortable and imposing, much like stolen robes would be.
