It was her college so she is entitled to wear it. However, we’ve never seen pics of her wearing it before and it’s a very well known Diana look.
You could argue it’s unfair that she doesn’t get to wear her uni sweatshirt, but at the risk of being accused of cosplay…..I think most 43yr olds would forgo the college sweatshirt while putting out a video to millions.
What I will say…..she certainly likes a drink 👀
