Can I Wear Jeans to a Job Fair? Usually, business casual is the best choice of attire for job fairs. This means no jeans, sneakers, or t-shirts. You want to show that you’re taking the event seriously and that you’re a professional. If you're not sure what to wear, it's better to err on the side of caution, even if that means you're a little overdressed. You're also likely to feel more confident when you've dressed your best, which will make a big impression on potential employers. Different industries may have different dress codes, so keep this in mind if the job fair is focused on a specific company, industry, or job type. For example, if you're attending a job fair for tech jobs or an open house at an industrial company where dress codes are more relaxed, jeans and a collared shirt or blouse may be perfectly acceptable. On the other hand, if the job fair is focused on companies that require employees to wear business professional attire, you should dress accordingly. If the career fair specifies a specific type of dress, follow their dress code. Otherwise, business casual is usually your best bet.
