If there is no company policy against certain attire,then it is all right to wear that attire-for example,flip flops.

Even if there is no specific company policy against certain attire, it's important to consider the company culture, the nature of your job, and general professional standards before deciding what to wear. Flip flops, for example, might be seen as too casual or unprofessional in many work environments, regardless of the absence of a specific policy.
