You should know that Guerlain reformulated L'Heure Bleue recently. To my nose when quickly sampling the current EdP in Paris last April it seemed that (part of) the florals were replaced by synthetics, which made it sharp. L'Heure Bleue is all about the floral harmony, the heliotrope note in particular, to me, which I find presented best in the EdP. Vintage (brown) jus on ebay (EdT and Extrait) tend to bring the base to the foreground as floral notes are vulnerable and less longlived. I'd try to find a slighltly used EdP from a perfumista, which is a few to a couple of years old (check batch code on bottle bottom by using cosmeticswizard.net).
