How do the clothes relate to the story?

Clothing is an important part of the story, particularly in terms of Percy, and the way other people perceive him. Percy is dasing, some people describe him as a fop. He overdresses, pays far too much attention to his appearance, and in turn, makes people see him as a person without substance. I's almost as if his clothing is a disguise. Percy's clothing would never expose him as the brave and daring Pimpernel.
