I've bought Donegal.  Now I've bought Harris - again.  Yet I'm still in two minds about it.  The Donegal I find pleasing, although I would say the jacket is borderline Ivy, nothing more.  The Stanley Blacker Harris is more Ivy in its overall look (but darted, ouch).  I was examining Harris tweed jackets in a local country store (now closed down) in 2018 and thought them highly sodding awful.  The owner swore blind he never sold anything from China. 
I dunno.  Moose said he thought they were too heavy for Ivy (at least, I think that's what he said).  Others disagreed.

^ Seconded.

Wasn't there once a 'blog' called 'Heavy Tweed Jacket'?  I was wearing tweed jackets before I ever knew the phrase 'Ivy League', just as I was wearing, on and off, moleskins and tweed overcoats.  They were simply 'an alternative' to what I was seeing around me: middle-market leisure wear, in John Cooper Clarke's immortal words (only it comes out as 'leesure').  It was deliberate 'Old Man'.  Most of these jackets would have been Harris.  Maybe all.  They used to turn up from time to time in charity shops - now they seem to adorn most 'vintage' shops.  I saw an entire rail of the buggers in Chester back in 2011.  Something to do with 'Doctor Who'.  It was the Blacker name that sold me on this.  It's intended to be worn with a flannel shirt, Levis and sneakers.

I've always like an HTJ, I bought one from BB's in Regent St in 2010, non darted, two patch, but 4 button cuff, first time I wore it on a visit to Chiltern St,(just after they opened I think),  JS admired it, asked where I bought it, then called to Paul ' Brooks are still making good jackets', no more I'm afraid, I got a Boston Tailors from Chiltern St 6/7 years ago, TBH I'm still breaking it in, got it for a ' negotiated' price, when I was there recently I think the full price of the few they have hanging around is about 850 quid,

@AFS, Heavy Tweed Jacket is another on IG.

Heavy Tweed jacket was the best trad blog ever imho. It had a big influence on me.

With my balding head a pony tail would not be a good look. It doesn't stop some old bald men, sadly. I don't do jewelry so no ear rings and tattoos a big no-no. I have been thinking about buying a gold necklace recently however. Too much mixing with my football mates I suppose.

Thanks for the tip on the HTJ Stax. I'm now under lock and key back in Finland with my wife watching my every move like a hawk. Freedom will return in January when I get back to blighty. I'll probably pay a visit to JS then
