It's what the expensive suit implies about the man's character, taste, and high social status that women find attractive.
There is a little truth in that, i think, but it's not the main point, according to my wife.
I think women just like clothes. Nice, fancy clothes. On other women, on men, on kids, whatever.
The main, sad point tho, is most women are *not* really attracted to the male himself, to the male body.
And i find this very, very odd indeed.
