Act 1 Scene 7
Lines: He hath'd honour'd me of late; and I have bought
          Golden opinions from all sorts of people,
          Which would be worn in their newest gloss,
           Not cast aside so soon.

Connecton:
Macbeth is speaking to Lady Macbeth and is comparing the enjoyment of praise and honour with the wearing of new clothes.  It also shows that as he gets more and more popular he gets better and better clothes, and as he gets more property , he gets more clothes. This shows class and style in connection with his clothes.

Act 5 Scene 2

Lines 23-25: Now does he feel his title
                    Hang loose about im , like a giant's robe
                    Upon a dwarfish thief.
Connection:
Agnus is seaking to Caithness about MAcbeth's power and that he is too small to take the resposibility of Scotland into his own hands. It shows  the image of clothes being related to power and fame.
