What an interesting topic! Brainstorming on it revealed that I have more classics/icon that I would have thought...and that most of them relate to a french countryside / mountain heritage way of life (which seems appropriate).
First of all almost the same as LJP : I gifted myself a classic Barbour Bedale jacket for my 18th birthday, and I still have it today even if I don't wear it very often (I don't even have a Find for it).
I also feel like Panama hats fits in there. I have both the iconic, original offwhite one with the black band and novelty versions.
Then, a handful of shoes/boots - mostly utility ones :
- Palladium desert boots, but mine are a remastered version with a side zipper.
- More niche, my garden boots are Le Chameau "Vierzon" (no Find for them either).
- And even more niche, the "1907 Megève" winter booties by Rossignol, that were not created in 1907 (the brand was). I'm not sure there is even an "original" version, since they undergo regular re-interpretations.
EDIT : I created Finds for the jacket and boots.
