My first time with pure parfum My SoTD was Geir and then I put on L'eau d'Issey Parfum about 3 hours thereafter. To my nose, Geir is the one which is more obvious. I've always thought the higher concentration would be the one more long-lasting and perceptible? Granted - the parfum was "splash" and Geir was spray...

I stand to be corrected.
