Gonna weigh in here on the "barefoot and in ripped jeans" that Meghan was wearing when William & Kate came to dinner the first time.
First off, while she was clearly Harry's guest, Nottingham Cottage was his home and I don't see a problem with her dressed in casual attire while staying there when they were dating. I highly doubt her "ripped jeans" were "showing off her private parts" for anyone to see. Meghan's version of "ripped jeans" most certainly is along these lines -

At most, she'd have been showing off less skin than you see when someone is wearing Bermuda shorts or capris.
None of those are disrespectful or even the slightest bit distasteful, but they're all high-end, which is exactly Meghan's style.
With regard to the bare feet... Lots of people, and I mean LOTS, myself included, take off their shoes as soon as they walk in the front door. Now, I prefer socks, but that's because I have issues with my feet, but I don't find it odd that Meghan was running around barefoot in Harry's home. Maybe a little odd while cooking in the kitchen, perhaps, but not necessarily. I lived in northern California during the same time Meghan was growing up and it was completely common for people to take their shoes off at home - not at all dissimilar to Japanese culture. Do I think it's odd that she didn't put on shoes or sandals before William & Kate arrived? Not really. Do I think William or Kate were in any way put off by this? Maybe? Maybe not? Obviously, they'd have been wearing shoes themselves since they were the ones walking across the Kensington Palace grounds to Nottingham Cottage for dinner. Was there some awkward "take off your shoes!" moment? Well, Meghan didn't mention it and I trust, had there been one, she would have, so I'm going to bet on no.
All this is, in this little docu-series, is another pitiful attempt by Meghan to make her seem the innocent, naive, casual, relaxed American walking into the completely foreign, stuffy, reserved, upper-crust British society. We've all seen Kate and Will (and their kids) dressed casually. Maybe Kate doesn't own any ripped jeans, but maybe that's just not her style. She's hardly alone in that, on either side of the Atlantic.
But, I don't think it's a big deal that she was barefooted and wearing ripped jeans, and I doubt Will & Kate cared one way or the other.
