So, I went in today and they had a charcoal peacoat from the Black Label line (first I'd seen) in a 57% wool, 27% angora, 10% cashmere, and 6% spandex blend. Those are pretty accurate, though I may be a percent off here or there.
Needless to say, it's approx. 1k on sale - should I go for it? The fit was spot-on for me, and I've been looking for a quality cashmere-blend or 100% cashmere blend.. I am slightly concerned with wearing something with spandex in it, though.
Unfortunately, it's not on the webpage so I can't show any examples.
