Curse you, Flo, I now want a Barbour (never thought I'd ever be saying that in my life) by Margaret Howell. Perhaps if your PM keeps up his antics and drives the GBP down further in value I'll put in an order. Although I fear it will be very oversized on me, if it had a padded winter lining I would have taken the plunge already.
I have to say AC's cool auntie sounds way cooler than AC herself. Then again I've never really understood the adulation of AC myself, I always thought she was a Vogue UK plant.
Time, it's probably worth looking at cheap wool/cashmere furniture throws, they tend to be a good size, usually a bit thinner so not a full on winter scarf but enough to keep you warm in a plane without a scary price tag and a more muted palate of colours on offer. My mother had a fab one from IKEA of all places, looked very lush and was all wool, lightweight and folded into nothing. I remember there were a lot of good links from Scotland on here when I was seeking out a tartan scarf, a lot sold a furniture throw as well in cashmere and wool mixes. Knitted silk can also be a good alternative but that will have a sticker shock price tag to match.
