Well, I'm not sure if this will help because I was under the impression that "Ritz" and "Charles of the Ritz" referred to the same fragrance, but it looks like they're different according to the directory (and neither of the reviews actually describe the scent - well, maybe a bit but "coppery" throws me off - so I have no idea which scent they're referring to, if they are indeed different ...as the database has been wrong before) so I'll just share what I know. I'm familiar with the fragrance that came in the canisters (I don't know if it's from '71 or '77) and it's a lush and beautiful aldehydic floral, but I don't recall any specific floral impressions....maybe orange blossom. If I were pressed, my closest guess for relatives would include No22, or maybe Lancome's Climat, but sweeter ...or a less sweet Boucheron, perhaps? But it was glorious, and I'd love to find some old stock - I think it would hold up quite well due to the packaging.
I went through two bottles in the early 80s - the silver canister that says "Ritz", and then the all burgundy canister. I've seen the frosted glass bottles with the leaf and it looks like that's also called "Charles of the Ritz", but I'm suspicious of that one for some reason, probably because I've never seen it in person, although it says "original" on the bottle so it could be a more recent re-release...? I've also seen the smaller all glass bottles that say "Ritz" on some, and then others with the burgundy labels that say "Charles of the Ritz" - both of these, I'm pretty sure, contain the fragrance that I know and love, but the only one I can talk about with any certainty comes in the canister.
Lol - I hope this sheds some light on it, but I get the feeling I might have just enhanced the confusion.
