Many women dream of wearing sandals to the office and still look professional. That depends very much on your work environment. If there’s a strict dress code, you’d better stick with pumps or stilettos, if you feel comfortable wearing them for many hours. At best, you can try peep toe pumps. These can look professional enough, but you will have to have an impeccable pedicure to show. In certain work environments, even slingbacks or mules are acceptable. As a general rule, keep in mind that open-toe sandals are not considered professional.
