I keep a little notebook for things that come in and go out of my wardrobe, so I wondered if others do, too? I understand some folks have very high-tech spreadsheets linked to their monthly budgeting, so my system may be a little quaint!
Anyway, just the simple list of outs on the left and ins on the right--usually start a new month per small page just because it's easy to do so--does help me some.
My goal isn't so much to have a tiny wardrobe but I think I have plenty of "items" so if I'm bringing in more than goes out, it usually means I'm not thinking about purchases well enough, duplicating items or looks, or I'm not deciding to let go of things to move on to new wardrobe style or upgrade, or all of that.
I'm not rigid about one-in/one-out on a weekly basis, but it does make me stop and think--if I thought I needed to bring this item IN, why, exactly, is there not something going OUT? Is it a new clothing need , as in, I've taken up mountain climbing (I haven't!), or is it cardigan # 17?
2012 was the big de-frumping wardrobe turnover so I had lots of ins and outs for some months. Now I'm having to be even more critical because of the things I have now, I have to decide, do they need to go through yet another round of cutting, or if I like them, I should not just shop and get something else that's similar.
So, writing down any new purchases helps keep me more accountable. It's important for me to write it in BEFORE I take off the tags and wear it, because a few times that's helped me say, wait--this needs to go back because my in column is exceeding my out column for the month (or whatever time frame ) and I can't honestly say there's anything in my closet that I like less and would toss out, so it's evident that it was not really a PPP purchase.
