I'm a pasty-ass and I look best in the colors at the bottom because I have a cool undertone and even cool pastels wash me out. This isn't good advice.

Finding your season is helpful though! I'm a winter and it made shopping a lot easier once I figured it out and I knew how to streamline my options to pick colors that I feel confident in. I had figured some stuff out on my own but didn't understand the underlying reasons, so clothes shopping was still kind of haphazard until I understood why some greens were good and some greens were bad, for example.
