I was able to get a decant of vintage Joy parfum (extrait).
My god, this is the most beautiful floral I've ever smelled. It really is a joy to wear.
It's like running through a field of every fragrant flower in the world on a dewy spring morning.
If you haven't tried this yet, please do. This is one of the most beautiful things I've ever smelled, and really fits the bill as to what a "fragrance" is - an enveloping, timeless experience. Jean Patou really is one of the best houses of all time.
