Yes truly wonderful a fragrance.
Don't worry at all. Your bottle is in perfect condition. The off-putting smell - for the first 10 secs or so - is what I've always experienced with all off the AA bottles I have emptied.
To me, it's always reminded me of baby diapers LOL.
I've attributed this to the ambergris element, although ambergris has a different stench that usually fades into a magnificent dry-down, which I also get in AA's dry-down.
I wouldn't know about your sample vial, but maybe that's the case with it because of the synthetic ambergris that's used in its new formula, since genuine ambergris is not allowed in perfume making anymore?
