9．What we wear at home is our own business．We can dress freely at home．No one will care or debate about it．（26）G．Why？That's because the way we dress affects us and other people．It is basically a matter of self respect and respect for others．
According to a famous behavioral economist，humans have a pattern of irrational（不理智的） behaviours．One of them is called"the effect of expectation"．Ariely says that when a person believes beforehand that something is good，he will look upon it generally as good．（27）C．If you wear a cheap old T-shirt like a beggar，the respect and expectation that you gain from people around you will be poor．
Some people might argue that we should have the freedom to dress however we want regardless of what people think．They can also argue that we should not judge people based on how a person dresses．（28）D．People judge us based on how we look，and that is a fact that we should accept．
In fact，we don't have to spend a lot of money buying the most expensive clothes．It doesn't make sense to go to a supermarket in a tux （晚禮服）．（29）A．Experts suggest that we should have various levels of dressing．For example，level 1：dressing for staying at home，level 2：casual dress for going out with friends，level 3：formal dress for work，level 4：attire （盛裝） for business functions and so on．
（30）B．When we choose clothes to wear，we should be aware of how it makes us generally look．At least we should be aware of it instead of just wearing it and going without giving a second thought．Dressing up is how you"sell"yourself so don't take it too lightly．
A．The dress should match the occasion．
B．It is helpful to have fashion awareness when we dress．
C．Therefore，the look is important for a first impression．
D．That is pretty ideal，but it is not practical in the real world．
E．It changes people's reactions towards you in a positive way．
F．Therefore，it is a good idea to be aware of how we behave at home．
G．However，when we dress up and go out to public places，it becomes an issue．
