This is the post I needed last summer when I was trying to distill my style from all the clothes I owned! Using just a few favorite outfits makes *so* much more sense.
I clearly can't do this right now, with the odd, lopsided collection have here now. But I did choose what to bring and what to store or give away based in part on happiness factors. When I'm sorting all the rest into a closet in a month, I will watch out for themes, and may set aside a few very favorite items/ outfits to analyze.
As several people noted on my recent WIW post, I'm much closer to my "real" self and style here than I was in Tampa. The one element I'm missing is the intellectual stimulation of work, which certainly affects my thinking and style.
