When shopping for your interview clothes, some trade-offs you face include: whether to get a job or not. choosing one brand of clothing over another. choosing one type of clothing over another. time and money that could be used on other things. The opportunity cost of buying new clothes is: time off from watching TV. the choice of what to wear. the choice of where to shop. money that could be spend elsewhere. The benefit of buying new clothes is: feeling better and having more confidence. learning about clothing options. being able to discard old clothes. finding the right sized clothing.
