While constructing your work wardrobe, you might have wondered whether open-toed shoes are okay to wear with a business suit. Generally, they're not. In most business situations and corporate environments sandals, open-toed and open-heel shoes are not considered professional. This also goes for many types of heeled shoes that may be considered too dressy, sexy, or otherwise overstated. You can very likely find many shoe-sale sites and fashionistas who will disagree for their own reasons, but when it comes to certain business functions, formal business rules apply especially when interacting with clients, attending important business meetings, or simply even trying to make a good impression and get ahead.
