Why can't you wear black shoes and white socks? Is there anything special?

This is a taboo of etiquette!

When wearing a suit, the colors must be coordinated and the overall color should be consistent!

When wearing a dark suit, you must wear black shoes, so the color of socks must be dark! Black is the best!

And socks must be pure black! The length can't be too short, and it's best to make sure that you don't show your legs when you cross your legs!

If you wear a dark suit and white socks, you will be laughed at by others!

If you wear a white suit, your shoes and socks must be white and spotless.

To sum up, when wearing black shoes, you must wear black socks!

I hope my original answer can help you!
