I'm saying that it is ACCEPTABLE to wear jeans, even in a professional setting. Jeans are "smart business attire." (If the dress code were "formal," that would be something else. But it isn't.)
Did I make it so obscurely?
EDIT: Actually, the poster above was not accurate. The dress code is found here- https://www.fide.com/docs/regulations/wrbc_regulations_2024_...
And it was much more precise than "smart business attire.".
