It can't be too surprising that in a thread about royalty, people will be knowledgeable about royalty... I'm not sure why it's so challenging and time-consuming to type a correct title than an incorrect one; it's not like this is what will make a post too long. But to each their own.

To each their own, indeed! As I've always said myself on a number of occasions.
I think there are many more royalty experts on another forum that's specificially dedicated to discussing royalty around the world, than there are here on FSU. As far as writing out long titles being a factor in making posts too long, that never entered my mind.

Obviously, it's fine to be as correct and proper as possible on every occasion. On Internet forums, hmmm, good luck with that. As it is, there's all kinds of jargon and abbreviations used to reference ice dance and pairs partners. Yep, I know none of them are royal, except perhaps for Diva Aliona.

In any case, I'll likely reference The Duchess of Sussex first, and then switch off to Meghan, Megs, Duchess Meghan, M&H, or whatevs.

As far as Catherine, Duchess of Cambridge (or more appropriately HRH The Duchess of Cambridge), at least she's no longer being referred to by the tabloids as 'Waity Katie.' An awful moniker for a perfectly delightful lady who will one day become Queen Catherine. On Prince George's birth certificate, it was written out for mother: 'Catherine Elizabeth' followed by 'HRH the Duchess of Cambridge.' Her occupation: 'Princess of the United Kingdom.'
Speaking of the beautiful royal Duchesses, here's video of their fun day at Wimbledon:

Interesting but speculative, and I think Meghan is not adopting Harry's persona at all

Another clip stated that the Duchesses met with former women's champions at a luncheon before match play began.
Re the long Ralph Lauren pants, eh. I've seen Meghan wearing these type of long pants before, in Scotland earlier this year, and a similar pair of wide leg long white trousers at a pre-Harry event some years ago. It's a style and it works for some people. I have a pair of black pants that fall similarly, but they don't have quite as wide pant legs. Any type of pants and pants cuffs are gonna get dirty anyway, especially if they're white. As MacMadame said, Meghan don't have to worry in the least these days about washing and caring for her clothes.

It's surely nice to be freed up from taking care of mundane tasks. She's got other more weighty matters and logistical planning to take up her time, in addition to spending quality private time with her new hubby.
Catherine, Duchess of Cambridge, is the styling of the Dowager (i.e. setting aside the other titles for a moment and the whole will be king part,
Thanks. Then Wiki is way way wrong with their 'Meghan, Duchess of Sussex' compromise.

Jeez, there should be a proper university course offered to study up on all this British royal protocol/ British royal titles nonsense.
The principalities of Monaco and Liechtenstein kept it simple, sweet for Princess Grace, and Princess Angela respectively.
