I was working in J.Simons when a truckload of coach jackets arrived from the States. Everyone went bonkers for them,  but I wasn't impressed, and looked like a complete tit in one. John also once got hold of some very rare white USA Weejuns and seemed baffled when I scoffed at the notion of wearing them. The Small Faces had poisoned my notion of white footwear, though JS looked great in his with his little chubby tanned legs. The Burberry Trench 21 I once thought the essence of ugliness but can now perhaps grasp its appeal.

Of course there are people who disdain the entire Shetland crew neck, college scarf and Gloverall look between late October and early April: a definitely kosher Ivy look in my humble opinion: especially when wearing Bill Evans or Bobby Peston-type specs.

I can't quite get my head around Paraboots, as part of that french/british look. Other items just don't translate to a British take on ivy - even if you wanted them to, which I don't - like bow ties. There's definitely a more-or-less subtle class politics to what travels well across the pond. Blazers with gold buttons would be a less extreme version of that (change those buttons out for pewter or something neutral!). Cable knit jumpers.

Certain things in the Ivy cannon simply don't suit me.
A Harrington jacket for example.Makes me look top heavy.
I also remember them being worn by skinheads in the Eighties.
Funny how in the Eighties white loafers were popular. I owned a few. Worn without socks. They just feel a bit garish now.

White Sperry Topsiders a la Tom "Selleck" Magnum, although I actually bought a pair in Kermit Green, which when I realised I'd made a big mistake I sold on to a mate 2 weeks later.

Went back and bought the classic brown.

Horace, I'd agree with much of your last post.  British (English/London - certain parts of) 'Ivy' has a peculiar history all of its own.  It would take a poster like TRS to explain it away.  But there was always 'cross-pollination' (plus the fact that young teenagers wearing, say, tasselled loafers circa 1971 probably had little if any idea of what it was all about.  But, heavens above, Oxford bags were being worn here).
