Joanna AddedThursday, April 25, 2019 at 8:36 AM What does a petroleum engineer wear? I am a 5th Grade student and making a project for school about petroleum engineers. I am doing GREAT, but the only problem is that we need to dress up as one. I did my research but still don't know what to wear. I will be so very grateful for even the little details. Thank you!

If they are in an office working on designs remotely, they will usually wear clothing that is appropriate for their office. If they are out on a construction site they might need to wear a hard hat and a safety vest. If they are meeting with clients they might dress in a business suit or something more casual depending on the client. For your project you could probably get away with wearing a nice "business casual" outfit, which may be similar to what you wear to school every day.
