I'm finally sitting down and reading through this whole thread -- what a treasure trove of advice. I thinking pushing oneself to come up with a set of descriptors and a moniker (and accepting that these aren't something set in stone, that they'll have to evolve with you over time) can be hugely helpful. Angie's suggestions for you are so evocative, I think it's really just a question of deciding which direction you want to take.
I'm thinking that there's a sort of ruthless artistry to a good closet edit. Knowing what to leave out, how to pare down and get to the essence of something, is so fundamental to good writing/art/music, that it makes perfect sense that style would be the same. So, yeah, you're a Style Virtuoso, and I hope you find the perfect summer refreshers.
Oh, and I wholly endorse buying pants, jeans especially, in a couple different sizes when you find a perfect pair -- I've started doing this shamelessly over the past couple of years. I was really resistant for a while, for all those same vanity/body-image reasons, but then I started shopping vintage pants and it really hit home for me that the size on the label is completely and utterly meaningless. What counts is that the rise is just right, the legs are cut just right, the pockets are in just the right place, etc. I think this strategy works well if you want a core set of classic pants you can rely on for several years going. If you chase pant trends it doesn't make as much sense to duplicate heavily, but pants-shopping is just too time-consuming for me to embrace every trend that comes along.
