It's likely to be pretty warm but there's a chance of showers, lots of walking about and lots of sitting around. It's over 2 days. So far I've put a Peter storm rain poncho in my case - very elegant 😁. I can't get away with shorts as I'm old and fat. I want to feel well put together in a casual way and to be comfortable when sitting for hours and hours. And hours.
What would you wear?
