For a wedding planner, you will get to handle all kinds of people - different nationalities, culture, traditions. Perhaps you need to study the culture of your potential clients. For example, an Indian bride is given a treatment not the same as the bride in other Asian countries. Africans is another example. You have to know the culture and tradition so you will know what is allowed and what is not. It's difficult to go into details but I guess you already get the gist of what I am saying.
