Which side of a womens blouse are the buttons?

The buttons are on the left side of a woman's blouse. The buttons on a man's shirt are on the right hand side. It is thought the reason being is because in Victorian times, women had maids to dress them while men had to dress themselves. With the majority of people being right-handed, having the buttons placed on the right side for a man made it easier for him to button them up by himself.
