Harry and Meghan are still very popular internationally- so if you give them an award, you get international attention for your organisation/any organisations you are trying to promote and so it’s worth giving it to them. Also they will turn up, not send a representative.
Rather depressingly, the big difference with Meghan’s look is she seems to have lost a bit of weight. As a fellow middle aged woman, I do hate that the answer to looking better is often “lose a bit of weight”. It’s in the same vain as realising the people who tell you to drink more water and give up sugar/coffee/wine and go to bed early are right, such things will take 5 years off your face. <sigh> why isn’t the solution ever “eat the cinnamon bun”?
