If you look carefully, those handsome guys are wearing black socks or dark socks, which is enough to prove that black socks are not ugly.
In addition, boys look good in black socks, which can improve one's taste. Nowadays, wearing too many white socks is too vulgar, and white socks are easy to get dirty and difficult to wash. Wearing black socks is better than wearing white socks with flowers. So black socks are your best choice!
