FACT ABOUT SHIRTS...

Men’s shirts have the buttons on the right, but women’s shirts have the buttons on the left,Why?

Because men have always tended to dress themselves and most men (and women, for that matter) are right-handed.

Women's Shirt buttons are on the left side because years ago (say, during the Victorian Era), the women that could afford fancy clothing with a bunch of buttons would rely on maids to help dress them. So, if a servant (most of whom, naturally, would be right-handed) is going to routinely buttoning up a shirt/dress for someone else, that servant is going to prefer to have the buttons on their right side (which would be the left side of the garment).
