Well, my sewing skills are non-existent, so I am going to just bite the bullet. I washed the bra I wore 2 days in a row and it does feel softer/lighter than the one I haven't worn yet. That will go in the wash before I wear it.
I'm having some weird allergy issues now and I think my body is on high alert. I seem to remember that this happened last year, sort of around this time, maybe late Feb./early March. So, it might be wool related, like a cumulative effect, but it also has to do with my emotional state, which is getting a little nervous about finding a job...
