i have wool jersey cropped pants from cdg-as comfy as sweats...but more stylish...
a long slv t cashemere sweater tied around my neck...(i put it on once on the plane)
i usually wear my yohji wrestling shoes on the plane...cause they are completely rubber and security leaves me alone...i never have to take off my shoes...and they are comfy to run around the ariport in...
then i bring a cashmere wrap with me so i don;t have to use the scary blanket on the plane..plus it comes in handy if the nights get cooler...
thinking it might be pretty chilly in london this time of year...worried about packing...
