Obviously I could wear jeans and trainers, and that would be fine. But I want to dress up a bit because for some reason I don’t seem to have done that for a while.
So probably a knee length A line dress or skirt.
Practical considerations are that I’ll be walking about a mile and a half over the course of the evening in four installments, and it will be raining.
I have a comfy pair of Geox wedge sandals but they’re not ideal for rain.
I’ve got silver Superga’s, brogues, low heeled red courts, and comfy pointy toed kitten heeled ankle boots (not exactly on trend, but it’s the Golden Age of Broadway at the Proms - at fifty I may be the youngest person there). Probably other things as well if you mention them to me. Also a wide range of tights (surely not in July though) and trainer liners.
