^to rach's interesting post above, I think that "it looks good to me because it looks good to me" is an entirely valid justification for one's preferences over art or clothing or whatever. If this idea interests you, it's possible you will enjoy this thread: http://www.styleforum.net/t/306673/on-the-utility-of-rules-for-dress-and-fit I think hoping for rational arguments on clothing is something of a fool's errand. We can look for patterns in things that we like to try and produce more things that we like. But we take as fundamental our preferences, not these rules. An example is the color wheel. We have learned, or some think we have learned, that some pattern of colors from this wheel work well together, no matter how the wheel be rotated. This is a theory, which then must be tested by our preferences over these different color combinations. If we find a combination of colors that "should" work, based on the theory, but that we don't like, it is the theory that is wrong, not our preferences.
