As a Rochas devotee myself from when I hit my 20s, have to say the brand has never been all that easy to find - one of the reasons I always loved it, since it was rare for me to bump into someone else wearing the same scent. Rochas did become more popular - in British department stores at least -in the mid 80s to mid 90s and you could usually count on a good-sized concession in higher end places, but these days???!!
Since my two all time favourites from the line - Mystere and Eau de Rochas - have been discontinued for several years I've been relying on discount perfume stores actual and online who specialise in discontinued oddments for my supplies and even those supplies have now dwindled to none. That's actually what brought me to this site, bowing to the inevitable, I was looking for a replacement for Mystere and stumbled across this place.
