Buns, more elegant chingnons, are indeed the unsexiest hair-do for women a lot men say.
The higher on the head the more hated by men and the more comfortable for many women.
A glance back in history shows in the ancient Greece it was worn by Athenian women first. But later by different men, too. For example Anthony Trollope, one of the most successful, prolific and respected English novelists of the Victorian era, wore a bun.
A famous bun girl is burmese democracy leader Aung San Suu Kyi.
So maybe men you are wrong and buns are french chic and not only the hair-do to wear when you are out of sight.
We love buns on our heads and also on the ones of bearded men.
So be careful of bun bearer crossing the street.
