Virtual interviews and casual work environments are making it harder for job candidates to know what to wear to interviews. Career advisers long recommended polished suits and other types of business attire. But that's no longer the safe choice when the interviewers may show up dressed in hoodies and shorts. Stylists say a well-tailored suit still is the default for executive roles and jobs in fields such as law and finance. Beyond those areas, it's worth exploring an organization’s culture in advance. A hiring manager or recruiter can answer questions about the dress code. Getting it right, or wrong, could affect your comfort, confidence and performance during an interview.
