Ankle socks are treated as something that should not be worn with sandals for some reason.
It doesn't look very good. But times have changed, and some people wear socks on sandals or
shoes because of the retro wind. On a fashion or girl group stage, you'll find occasional matches
of socks with the right patterns and materials to the right shoes. But it's pretty when the proper
coordination is supported, not the combination of uncle sandals plus socks. If celebrities go out to
the airport wearing like that, they will be called a fashion terrorist.
