Not being a follower of fashion or having extensive knowledge about it, I don't know much about whether the niche is saturated or therefore lacks competition, but if the case is that there is not much competition and it is a niche to be exploited in certain areas such as forums, it may be a good idea to try to get into the niche, I agree, if you are passionate about fashion and like forums, it can be a good businessWhen you look at this very closely, you can actually find out that there isn't much forum based community that is on fashion niche. This is actually a very good idea for someone to start a community that is based on fashion niche. I don't know what you think about this but I believe it's something that can actually head in a very right direction if someone have a very good plan for the project.
