Of course:
The expertly fitted suit compliments, thus enhancing an appearance of health. The significance of this to the Biological Imparative is well… now academic.
But modern natural selection adds more:
The flattering suit comes at at least some expense, suggesting the ability and will to provide for the offspring.
As for the meaning and the aesthetic, for me they are one and the same:
A complimentary and quality suit is not only simply attractive but it tells the sort that I wish to interact with that I know some things.
Why a particular fabric and much more importantly cut succeeds is not a mystery to me or the result of an accident.
It tells certain others that I know the rules, and know which ones I can break in the name of style, or should I say MY style.
In other words, I also possess creativity.
