I’ve been very fortunate in my life to have not dealt with much sickness (I can laugh now about getting chicken pox just in time to go on my first real adult vacation when I was 22 — the perils of working in a school, as I got strep, chicken pox, and pinkeye all in the first year, for the first time in my life!). When I don’t feel well, I will just wear my usual pajamas or loungewear — whatever works for that season.
Like Deborah, when I had abdominal surgery 7 years ago, I made sure I had a small capsule of loose elastic and drawstring waist pants, loose dress, and comfortable underwear for the weeks of my recovery. I remember attending a semi formal benefit dinner with my husband only two weeks after, and managed a nice skirt (stretchy waist), top, and lace blazer for the event. He was impressed I even chose to go!
