In the days before I found YLF, I had a lot of clothes (150-200ish). Very few to them were great on me, and most were purchased either for a specific event or because they were on sale. I frequently accumulated more whenever I found a good deal that appealed to me. I sought variety because I was unhappy with my wardrobe and didn't understand my style.
In the first year an a half of finding YLF, I purged the majority of my wardrobe, and then replaced it. I made better choices that continued to improve over time while also making some mistakes that I learned from. I sought variety to try out new things, figure out what worked for me (and what didn't), and because there was a lot of advice floating around the web about which items to stock up on (like jewelry) to increase wardrobe remixing options.
In early winter 2010 I began to actually track my purchases, how much I spent on each item of clothing, and how often I wore everything. I was buying "investment" pieces, but I couldn't wear them often enough to make them worth the money. I was also buying items that I wasn't entirely sure about, and then not wearing them often, even if they weren't very expensive. I play favorites, but it wasn't until I recorded what I wore every day that this finally became clear to me. This tracking led to a new, more sustainable round of purging and gradually to more judicious consumption. But I still spent a lot of time craving variety and thinking about clothes, and a lot of time feeling guilty about how much money I had spent in the previous year and a half on items that I was now purging (like much of that jewelry).
In December 2011 I realized that I needed to start devoting more time to my academic work and non-internet social life, and less to YLF and fashion. I'm still tracking what I wear and weeding out the occasional closet orphan (I'm down to 66 items of clothing, 6 pairs of shoes, 10 accessories, and 26 items of jewelry, yet there's still some slack), but I haven't been around here much, and I have become excruciatingly picky with my purchases. Overall, clothes are taking up far less of my time (though still a bit more than they did pre-YLF) and remixing provides all the variety that I need.
My shift towards a more simpler, remixable wardrobe that I LOVE would have been impossible without YLF. It's still a journey, and I'm hoping that I'll be able to increase my YLF time this summer without backsliding into a place where I am unhappy with my closet and driven to consume more. I don't need more variety than I have and I know from experience that buying (or even pining after) a bunch of new items isn't going to make me happier with my wardrobe.
