Although in all the cases proposed the reasons for the distinction no longer exist, it continues out of custom or tradition.
While most women prefer to have the top button open for better comfort, some blouses made for women have looser necklines so the top button can be fastened without compromising comfort, but giving the same stylish appearance.
Some women attach various pins and ornaments to their blouses over a fastened top button for style. Some of these attach directly to the button itself, others to the collars.
Some blouses do not have a top button at all, and collars are styled to be open. They also form part of some nations' traditional folk costume.
