EISEF has no dress code as such. You should wear clothes that will let people know you are a serious student and you take the competition seriously.
What’s more, people will be taking pictures all during the Fair: during the Orientation session, at the exhibits, during the Awards Ceremony. We’ll post many of these pictures to our web site, and some may even appear in your hometown newspaper. (Read our Privacy Policy.) Take a look at the pictures we’ve posted for previous Fairs. Imagine searching the web years from now and finding a picture of yourself on our web site. What would you like to see?
