In here a little late, but...
We go to a public laundromat, so my underwear is thrown into the wash with everything and then into the dryer. My gym bras, however, only go one dryer cycle as opposed to 2.
I bought a thong and wore it a few type, but it was way too annoying. This Ms. Practical swears by Jockey For Her high cut briefs, most comfortable underwear I've ever worn.
I always disliked pajamas and started sleeping in the nude when I was around 20. Been that way ever since until last winter, when 3 nights in a row I woke up in the middle of the night and couldn't fall back asleep because I was so freezing. I finally got a long-sleeved night shirt in t-shirt cotton and I wear it late fall and winter. My metabolism musta slowed down with age because I'm freezing a lot, and this is Southern California where it doesn't even get that cold. My husband, of course, takes it as a personal affront, but then, he takes everything as a personal affront.
