Knitwear
As daggy as it may sound...I do like Speedingbirdhouse's suggestion of knitwear. Oh I miss my old Harry Who cardigan, it was fabulously warm and was great to wear when sleeping. I used to secretly wear it under my jacket to keep warm in freezing ports. I think a stylish woollen neck scarf would be great too.
Oh, knowing Qantas, if they were to introduce knitwear, it would probably be fire retardant acrylic anyway....as if they would give us wool again!!!!!
