No, it is not advicable to wear a casual shoe paired with a formal attire.
This combination will look out of place if you are going for a meeting or interview. Your footwear can make or destroy your entire look. It is better you don't experiment with your shoes when going for such events. Wear a shoe that fits your formal attire.
However, the fashion trend is slowly evolving. Many are combing casual shoes like sport shoes on formal attire. But it is not professionally accepted by many.
So, if you are going out for fun, you can try this but if it is for anything professional, please do not try to combine both.
We strongly condemn wearing casual shoes with formals. This rule applies to all formal situations, especially interviews and meetings. Including formals with formals helps to portray a sense of refined fashion. However, if you belong to the fashion industry or your business or office is relaxed with the dress code, you can attempt to carry the look if you can pull it off.
However, most businesses don’t appreciate casual wear and employ strict rules against it. They require employees to be dressed formally and portray an elegant, primed up look. Hence, it is best to first look up the dress code before making a fashion statement.
