In my view not only clothes but clothe's color also matters in individual's personality. In other words science had proved that different colors create different influences on human being nature. For instance light color can relax your nerve system as well as yours or others eye sight. On the other hand dark colors are helpful to attract people towards you like red and black color. Additionally, mostly people select or choose outfit's color according to their body shape or skin color to look more attractive.
However in some special cases, the clothes may have some effects. For example, when a little girl wears a very beautiful skirt, she might feel confident when she play with other children, and thus more or less she might change her behaviors. But that is mainly because yong children are still developing their own characters and how they behave is quite unstable and unpredictable. Not only the clothes, but also a story, or even a candy can affect how they behave. That is why early education and proper guidance are so important for children.
