The Western Cape native edged out the win over first and second runners-up Miss Colombia Laura González and Miss Jamaica Davina Bennett on Sunday night in Las Vegas.
USA Today has further details:
Nel-Peters, 22, recently earned her degree in business management at North-West University.
During the competition's Q&A portion, the newly crowned Miss Universe was asked about the most important issue she thought was facing women in the workplace.
