To an extent, I agree with what you said in regards to wearing all black. I see that a lot around here and it often fetches a lot of compliments. For some reason, people seem to focus solely on the 'fit' and forget there is more to style/dressing well than well fitting clothes. Its certainly one of the most important parts to building an outfit, but not the only one. Colour combinations are equally as important, which is maybe what you were going for here.
Although there are some exceptions to this depending on the look you're going for...sometimes darkness is essential
