We rotate four summer sets of bedlinen, and three winter ones. The minute the bed is changed the cat gets in with muddy paws and a ton of hair.
In summer I sleep either in just knickers, or knickers and a short nightie, in winter long sleeved nighties, knickers, and fluffy socks. I have a very nice white waffle dressing gown but never wear it. DP sleeps nude.
I do, however, always match bra and knickers.
