Comfort all the way. My typical journeys are in Y and if I do door to door in under 24 hours it's a short one. I wear smart casual but comfy so jersey dresses or trouser suits or trousers and a tunic plus a DKNY cosy because they can be used as a cardigan, a wrap, a pillow...
My big problem is dressing for climate. Am currently in Lusaka where it is around 28c. Am leaving Thursday night for home here it is currently 1c. Either I leave here in warm clothes and look ridiculous or I arrive home in clothes not suitable for UK in winter. Have to have layers to add. (Once arrived home in birkenstocks to find snow on the ground and while my husband brought a ski jacket to the airport he didn't know or think to bring proper shoes for me!)
