Sulis I don't think it's superficial and nobody is 'harping on'.
I enjoy following fashion and I enjoy looking at what other people wear. I might not choose 99% of it for myself, but it does inform my own clothing choices. Plus I can admire how others look (or not, as the case may be).
It's the Golden Globes awards tomorrow night in the USA, so I will have a look at what is worn on the red carpet. The prediction is the good old little black dress is bang on trend. 
I'm pretty sure that once Meghan is married, we'll see her supporting more British designers. That's what most of the Royals do. There's no doubt she will be leading fashion figure, as things we've seen her wear are selling out and high street versions will follow.
