I've always assumed it was a particularly transparent way to get us to buy two products. Anyway, I've been wearing rose perfumes for about two years now and u wanted a big change. Cue lots of happy sniffing and I've gone to the dark side with Diptique Vetiver. But I miss the florals. So I've taken to spraying a blast of one of my unfinished rose perfumes. It works. I'd rather have the one just right perfume though. Does anyone else layer perfume and, if so, which ones and why?
