I think your numbers sound good .
It’s a bit of work and very time consuming to do this edit so I am applauding such a thorough job!

I would hang onto those slips as it seems fewer and fewer dresses/skirts are made with lining. Shoddy quality is seeping in everywhere!
As for tights: I’ve gotten a lot more wear out of mine once I started thinking of them as another kind of long john or base layer. On cold days I wear them under jeans or leggings. If I do wear a dress, I layer 2 pairs of tights.

Not home and haven’t done the challenge. Currently very short on underwear as I am up a size but only have 5 or 6, I prefer around 8-10 (some of the smaller ones are only slightly small). A million pairs of socks, down from 2 million after a previous significant edit. Lots of cute patterns, short on solids.
Short in bras also as up a size. 2 black, 2 nude to me, and somewhere 2 better, less comfy bras I think I should be wearing instead of buying more comfy ones, one each color. I wear twice before washing unless sweaty or dusty.
PJ’s and loungewear need sorting.
