A stunning soccer fan decided to rock a sexy 'fit as she cheered on her team at the World Cup over the weekend ... despite Qatar's strict dress code.
Model Ivana Knoll -- who's known as the "World Cup's Hottest Fan" -- posed for pics in a revealing red and white dress while in attendance for the Croatia vs. Canada matchup on Sunday ... with her shoulders and knees fully exposed.
Of course, Qatar takes a modest approach to clothing ... and anyone who visits is strongly encouraged to follow the guidelines.
