there were no credible reports or official statements about Meghan Markle or Kate Middleton crying specifically due to an issue with Princess Charlotte's flower girl dress.
It's essential to be cautious about spreading unverified or sensationalized information, especially when it comes to private or sensitive matters involving individuals and their families. The media can sometimes exaggerate or misinterpret events, leading to inaccurate stories.
As with many events involving members of the royal family, some details might remain private or undisclosed to the public. If there were any issues with Princess Charlotte's dress or emotions during a particular event, it is best to rely on reliable sources and official statements rather than speculation or rumors.
