Although I do agree with the other's statements, I know exactly where you are coming from.
I do feel like everyone else when I put on my sand/beige coloured chinos which I bought years ago now, and the reason I started paying attention to what I wear is to be me, not everyone else. Although, just like you said, I do feel my personality still shines through in my outfit as I don't wear them with hi tops like all the boys out there and don't want them.
If you feel as though your wardrobe just looks like re-hashed fashion trends then you need to buy some more interesting pieces of clothing. Nothing is safe when it comes to fashion trends, so perhaps look for clothes with interesting details to make sure you still feel your wardrobe represents YOU whatever the latest trends are. A jacket with an unusual collar, bright formal shoes, a featered felt hat in a rich colour, etc.
However, if you really want your individuality to stand out when the future fashion trends descend, I suggest buying a latex yellow suit, with matching yellow shoes. Nobody will see it coming. Well, considering it's a bright yellow suit, everyone will see you coming. But the point still stands.
I have already ordered mine. In azure also.
