— It's a private ceremony, her own graduation, not in a church, and it's pretty much the last thing she gets to do before she signs her life away to her country as an adult in a few months. I think she's entitled to wear whatever she wants to cross that stage.
— After all the discussion about her sister's hem lengths and potential trouble (who would have thought we'd be discussing Leonor first?), you still can't actually see anything scandalous. Just her leg. It will be interesting to see what the gutter press do, considering she's a minor.
— I can't help but notice that despite being a princess at her own graduation, Leonor has nail polish on neither her fingers nor her toes, so I don't think she was trying to look especially provocative.
— Furthermore Leonor and both her parents knew this would be on the Internet, and no one seems to have had any concerns.
Alexia looks very nice in her white suit at her simultaneous graduation.
