Shoppers are just realising why women's shirt buttons are always on the left hand side. It's something you've probably never even thought about before, but if you look at a women's shirt, chances are, the buttons will be on the left.
After hearing the theories, some people say they're 'mind-blown'. On Twitter, one person said: “I *just* found out that shirt buttons are on the left for women and right for me. Wtf!!!!”
Another tweeted: "I was today years old when I learned that women’s shirts have buttons on the left side!”
