Pretty sure I’m the only person who knows it, but this blog tracks kidlit-related Miss Universe National Costumes!
(The original links are dead, but previously, 2013’s Miss Denmark Cecilia Iftikhar as The Little Mermaid:
and 2016’s Miss Sweden Iva Ovmar as Pippi Longstocking:)
The belated new addition, which I discovered thanks to sang’s sending me nonasuch’s tumblr post, is 2023’s Miss Finland Paula Joukanen as Little My!
