I’m travelling to Greece at the end of May for work. I’ll mostly be at work events (think air con in a conference centre) and need to look smart. Will have a day or two for sightseeing. What should I bring? I’m thinking smart trousers and top with a cardigan for air con, but what should I wear on my feet? Ideally I’d only have one pair of shoes but not sure if smart trainers will be appropriate…
