Look dignified, but not arrogant.

I would like to point out that a pleasant appearance is advantageous, but it can also be a disservice.

The danger is this: a person dressed better than others feels powerful and often begins to behave condescendingly. And this is repulsive.

Remember, the one whom you are trying to convince, a priori above you: he has the right to say "no".
So it is worth striving to look good, but not to appear the best.
