I think it depends a lot on who does the washing maybe? My husband does it mostly (I can work the washing machine but after lots of costly errors and pink school shirts he tends to do the bulk of it!) so he puts the laundry away. Therefore he's the most likely to notice when socks/pants/tights are in short supply. Not just for me and him but also our kids...
In that case if I'm popping somewhere where socks/pants are on sale I may well pick some up after we've have a vague "where on earth is all my underwear" conversation. But he is also just as capable of doing so too, and does.
I'm not sure our relationship is contentious enough for AIBU
