This is what i felt that class 5 would look like. I looked at people in the current society that we live in and felt that many homeless people held a more appropriate look for the people in a class five status. I felt that this would create a clear visible divide in each class and you can easily tell what person belongs to what class. Within the Play, the characters of Pete and Dot are this class and i feel that they are the forgotten members of society and would contrast nicely with the upper class members.
Looking on the other end of the scale i felt that it would be visibly interesting to create a clear contrast between the upper and lower classes. Many upper classes would have plenty of wealth and would physically look like they had a lot of money. On the other end of the scale you would have a person in rags to almost create an over the top contrast between the classes.
