Well, in my views i think its the influance an actor/charecter can have. Many people get influanced in their style, or even the charecter, the way they act and stuff. so here is an example, say smriti from kyunki, shes an example idol to most woman since they all want to be like her (for example, my mom! lol). i suppose hair treads, make up, clothes and stuff are mainly influanced from actors too since its the fashion label, some people are afraid to try their own thing since they make think it will look wrong, or it may be out of fashion etc.
