Well, I *don't* have wool long underwear. It's silk. I have a couple of smart wool base layer tops, which I can wear occasionally. I never wear wool next to my skin, except for the Kates and these smart wool base layers. But I am finding that on days when I wear my Shaks with a lycra or cotton shirt underneath, the itchiness develops over the course of the day. Also, when I wear regular sweaters with wool, with something underneath.
I am definitely going through some allergic thing that is being set off by something, maybe even stress (I am searching for my internship position for my last year of grad school). I am taking a wait and see attitude and trying to just let it pass. It's to the point that it's becoming even more than wool; regular cotton seams are bugging me, too. Guess I am just a princess!
