I dated a young lady of English extraction who I quite fancied. Her 'set' of young English extracted fellow college students, male and female quite liked a slightly older friend of hers, a very nice intelligent young lady who was not unattractive but to my Yankee mind was a little bit 'horse faced' meaning nothing very horrible just a bit elongated the way, you know. I quite preferred my young lass's more round faced gamin look and came to the conclusion that Brits had slightly different dimensional demands than Americans. I wish I could say I came up with a theory I was able to prove, but I was at an age of high testosterone and low impulses. I vaguely wondered if the facial peculiarities of the Queen (God bless her) were influential, but again, how was I to put this to a test, other than remark on the physiognamies of popular stars on either side of the pond.
I don't think this is any more sexist than females of both sides of the pond comparing say, Hugh Jackman with Brad Pitt, Jack Hawkins with John Wayne, Rowan Atkinson with David Spade...

As to Lucy Worsley. I don't consider her much to look at, and her speech impediment reminds me of Bashar Assad, but she's an example of someone who can transmit sexual appeal on infrared, right through the tube. (Maybe these new flat screens are more advanced than they let on, and can outgas pheromones).

She could just make history up in her head and spout nonsense and I'd lap it up like a cat with a dish of half-and-half in front of me. She could say something like: "And Henry VII's eighth wife turned out to be the aunt of Henry VIII's seventh wife and both showed signs of alien implants which is why the Tudor line were known for their third eyes." and I'd just nod and drool.
