It is interesting that naming the emotion/association of the gold skirt here helped to reduce it just a bit. I have had similar thought processes around items (furniture, a blanket) that came from my childhood home. Just taking time to fully acknowledge the sentimental attachment and then concede to myself that it was perhaps unnecessarily outweighing practical concerns (my daughter had no attachment to that dresser and didn’t want it in her room anymore), allowed me to let the things go, with peace (it helped that someone in need took the dresser and appreciated its features). And for me all this does relate back to Kondo and the concept of ‘thanking items for their service’, so it’s interesting that she was mentioned in the thread too. This is not at all to say you should get rid of your skirt; quite the opposite. But maybe there’s a gut feeling about whether you are ready to wear it or let it go. And if undecided by all means keep it and see if someday you reach for it.
