... All of which begs the question 'What is the Culture of Ivy in London?'

And the answer is that it's purely one of quality and style. The wearers of The Look are too diverse to sum them up in any more specific way. Yes, some are Modernists, but very few are Mods, and beyond them you have the majority: The Great Unclassifiables. 

Rarity is prized, that's a common bond, and also the enjoyment of a 'diferent' aesthetic when compared to run-of-the-mill English style.

The style's early champions in London were a mix of Jazz fans, Modernists and also the Working Class - But none of those elements define the wearers of the style en-masse today.

It's a 'sophisticated' taste in London perhaps, but one which plays with what the notion of that means - It isn't silk shirts and velvet. It's being 'in the know' about certain cuts, fabrics and styling details.

And it has no Upper Class connotations or links to Higher Education  - England already has its own wardrobes for those things which American Ivy was based on in origin. Ivy is classless in England because it doesn't fit into English society at all. It's an alien mutation.

After various ups and downs in my life I am once again a Public School Marketing Executive, albeit part time & looking forward to some kind of retirement now.
Mr. John Gall remains at heart, I think, a Working Class Modernist. He'll have to correct me if I'm wrong.
Nothing in common with each other whatsoever beyond Ivy. A very nice example of the reality of Ivy in my city, and John's adopted city, of London.

God bless us every one !

Worzel in a dinner jacket is an inspired example, by the way - From both our points of view...

Worzel is Worzel and ever more shall be so. The Dinner jacket is certainly a status item, but not from Worzel's world.

Worzel would gain a 'classier' appearance by adopting the status symbols of his world - Maybe a few crow feathers in his hat? A 'Tux' means nothing on him.

Thus an American can wear Ivy and look classier and an Englishman can wear Ivy and look suddenly 'other', somehow out of the class system sartorially speaking.

Reversing this, an Englishman will look classier in a good English suit of London Cut, but an American will look like he's all 'dressed up'... Or not, until he opens his mouth to speak in his twangy voice or displays his disgusting table manners... Then he'll look like a Yank all gussied up in English style.

- While an Englishman may well look all gussied DOWN in Ivy style... As he sits there making good with his knife and fork... A credit to Mummy & Nanny !


An aside: When Americans wear English style:

Considering how rude the online Americans have often been about the English who like Ivy it might be fun to tweak the noses of the Americans who like English style for a change... ?????

How dare they !

You can over analyse stuff, or worry about things that nobody much cares about any more. The William Wardrobe route.

Plus you are talking to a small band who might actually care - people who get their trahseez tapered - not just taken up, but tapered,
