ACTUAL Canon/Near-Canon Ages of Barbie movie characters because I am sick of those damned posts making rounds on the internet
I provided all sources that I could and identified which were pure canon (as in, stated within the text of its film), near-canon (any source outside of the film), and speculation if needed. Go and freaking educate yourselves. This mostly focuses on protagonists and the ages of their love interests but includes others as well.
If you find something that contradicts this list, let me so I can update/add as needed. However, you must PROVIDE A SOURCE or else I’ll ignore it entirely. And it can’t just be “I read it somewhere” or "It said so on the Wiki" you need to SPECIFY what the actual source is. For example: "X character is said to be "#" on the old Barbie.com webpage" or "Y said her age was 17 in this scene".
And now to reward myself with sweets for doing all this work
