Hello, thanks for asking. I am not sure with particular bottles. Some of them I've been having for two years - using them up gradually. Some of them I buy and use up pretty soon in a couple of month because I enjoy them a lot :) It also depends on the fragrance type. Easy summer fragrances usually go faster than potent winter ones. And it also depends on what I've been doing occasion-wise. Casual perfumes get more love at my place at the moment :)
