I have a few favourite scents:
Champion Ruby Tobacco, Tweed, Opium and Pierre Cardin colognes all immediately bring happy memories of my grandparents and parents to mind.
fresh/new leather shoes or bag, a lamb roast in the oven, coffee beans, hot chocolate, fresh hot popcorn, raspberry and vanilla body wash, hypnotic poison, black xs, calvin klein shock street edition (unfortunately a limited edition that I can no longer find anywhere), pure tobacco being dried out in an oven.
