Comfort and simplicity are key. Avoid static-prone polyesters (no matter how hi-tech, they always tend to itch). Natural fibres are a good starting point. Flat shoes, denim and a mannish shirt seems to be Elle Macpherson's airport uniform and she always looks like she was born to first-class privileges. Layers are good as plane temperatures are rarely stable. Scarves are perfect for the same reason - Kate Bosworth's will double as a wrap when the cabin gets cool. High heels rarely are (VB take note), especially when your feet swell, but Eva Mendes's fabulous wedges have just about won me over...
