There is room in the world for all kinds of styles. And I for one, enjoy seeing people rock surprising ensembles. But, I've witnessed some jarring fashion faux pas. I like looks that are cohesive. The natural eye likes complementary elements, and one of the first pieces of style advice I like to give is ask yourself if the elements of your garb are complimentary and cohesive. Let me try to explain the concept.
By "complimentary" and "cohesive" I mean, for example, say you were wearing a floral dress. You should avoid slick looking, geometrically shaped accessories. You should be sure the shapes of the accessories cohesive and complementary with the shapes of the main pattern and the mood of the look. Gentlemen, say you were wearing a pinstriped suit. You should be sure the scale and shapes of the pattern on the tie was similar to the scale of the suit stripes. And make sure the tie and pocket square fabrics suit the formality or informality of the suit fabric.
