Travel fashion

My hubby and I are going on holiday in February and I always stress a bit about what I'm going to wear on the plane. I like to look nice, but I also like to be comfortable. It's always hard getting the right temperature because I get so hot hauling bags around the airport, but then I freeze on board. Lastly, you have to consider what will go with the rest of the clothes you are packing.
Now I should be saving all my pennies for spending when we are away, but I'm really tempted by one of these perfect cardigans...

It looks super soft and what a nice colour! I'd love one to throw on since it looks lightweight but would also be easy to shed when I'm overheating and overexhausted from a longhaul flight. Bring on the holiday!
