I've never been before. It says no jeans (obviously) We'll be there and around London during the day, so I don't want to go really dressed up or I'll feel like a twonk.
It will be early May, I could pray the weather will be nice and wear a summery dress with a smart blazer or something? But if it's cold and raining....?
I'm 29 and a size 6-8 for reference, any ideas?
