I went in Athleta for something else and found these!

Would never have thought to look there because I thought it was all tights and yoga clothes, but these are thin and breathable, softer than a lot of linen, and flattering. I got the dark grey color. Granted they are casual, not dress...but that's what I was looking for.
I'm posing because a lot of YLFs were looking for the same thing. Especially on my "I would pay anything for" post. But these are less than $100, so even better. I would have paid more, but glad I didn't have to.
PS...they are apple friendly due to the wider waistband.
