Is it ok to wear stockings and suspender belt to an interview at a bank?
Yes, as long as the idea is not to let anyone know that you’re wearing them. The suspender belt should not be visible under your clothes, and you should not be planning to flash the interviewer with the tops of your stockings. In other words, your dress or skirt should be plenty long and loose enough to conceal whatever you are wearing underneath, especially when you sit down. This interview is not about your lingerie, but rather about your qualifications for the job. Stockings and suspender belts are irrelevant. If they’re unseen, no one cares.
