Has anyone been to a Royal Garden Party? Advice needed please.

[Timeandtune]

My son (mid 20s )has agreed to accompany me.

Problem is he doesn’t have a suit and has not worn a tie since high school .

I would gladly buy him a suit but he will get zero wear out of it - he is full time WFH .

If anyone has been recently can you advise if the dress code is more relaxed nowadays?

TIA

Our son went to one at Buckingham palace this month and all the men were in suits

You could also have a look in charity shops. Fraction of the price of a new suit. And he may not wear it often, but it's useful to wheel out for weddings and job interviews etc.
