I too was brought up in a home where there was china, glasses and cultery "for best", tablecloths deemed too good for daily use, and Sunday clothes, although my parents were not regular church-goers.
I decided as an adult to use my "good" china, glasses etc. but tended for years to have "good" clothes and "ordinary" clothes.
However, the clothes were those I wore for work, or those I wore at home, plus those that only came out of the wardrobe for job interviews, theatre-going, parties or funerals - I do still have clothes for parties and funerals and clothes I wear for gardening and housework.
But by and large - we have n ice things because we like them, so it seems mad to keep them " for best" - it will do me, presumably, no good if they are only used at my funeral!
