Which of these men's outfits is the most formal?

tia, "" White tie and tails" is most formal night wear, and "morning dress" is most formal day with a very tail suit and top hat. And there is Court Dress for state occasions - with breeches and stockings.

Am I right in thinking that the most formal style of all is "White Tie"?

I adhere to a fifth dress code: slob!

Player #107744436, depends who is wearing the tie!😉

Player #107744436, it would be a very revealing outfit.

A tie is not an outfit.
