I'm going to Portugal in July. For work, and said work involves going outside into the city and walking to a few places and generally being mentally switched on. It does not, however, involve being terribly formal - I can wear fairly casual clothes.
Am slightly concerned that I'm going to pass out in 40 degree + heat! I don't really have much experience of managing in those kinds of temperatures. Those who do: what clothes should I buy to cope? I am very pale, so I think anything too skimpy may actually create problems.
