There is no standard answer to 'why men's buttons are on their right side', but the prevailing one dates back to the days of armour. On the left a man would hold his shield, and on the right his sword. This would make their stance slightly turned with the left forward. Now having the clothing close left over right - and thus having the buttons on the right - simply provided more protection. An add
itional advantage would be that for right-handed men, closing the buttons on the right would be easier. Women who set fashion in the Victorian Age used to be dressed by someone else, so the buttons needed to be on the right for the servant standing opposite. Combining this beautiful history with the reality of disappearing socks, Button Right socks were developed. Before washing, the right sock is buttoned to the left sock. No longer is it necessary to recombine single socks, since they will have stuck together throughout the entire process of washing and drying!
