Is it OK to wear sandals with socks?
Yes, sandals with socks are acceptable when done as a deliberate style choice. The key is pairing chunky sandals or slides with visible crew or ribbed socks that are meant to be seen as part of the outfit. This intentional look is an established current trend, completely different from the dated accidental pairing that still carries a style stigma.
