For anyone else worrying, I went in the end, in my mid grey trousers and a grey patterned silky top with a black jacket with me. I wore the jacket in the crem but it was far too hot so I removed it when we came out. I needn’t have worried, there was all sorts of combinations of colours, predominantly black and white or a mixture of those. No one looked wrong, no one was bothered. As others have said, navy would have been fine. There were a couple I thought took casualness too far - trousers and a t shirt such I’d wear in the house but there you are. Lots of men in just a shirt, no jacket. It’s changed, along with so much more. Thanks for your advice.
