I've been famine-oriented, but am working out of that over the past year or so.
It's been a combination of personality/mentality and a lack of style focus. Improving style focus helps with narrowing down what I actually want to wear and having a a glimmer of a vision for the next iteration of pants or tops or silhouette. So there is some fun not in just having the right outfits, but in anticipating them. SYC and outfit creation have helped show that there truly is "enough" to keep me clothed, so is a reality check. "Enough" doesn't mean no more clothes, but means not having as much pressure to hold on or stock up on things that aren't 10's.
I think if I lived closer to a greater variety of B&M stores it would both help and hurt! I'd be tempted by all the good stuff that is too easy to bring home and might grow roots, but would also be able to try out more things more easily ( I'm lookin' at you, first-name-basis postal worker!). Trying a wider range of things keeps you aware that the "right" thing will probably turn up, or you can compare fits and not settle, or find a new direction, or replace something and not have to have too many dupe's. So I have to find ways to keep that same mentality going but not be inundated with packages.
So, more editing and tossing is underway! It also helps me keep whittling down my "holding zone" to fewer items which have specific purpose in the ebb and flow of fashion and lifestyle.
