I wanted to try Dior mascara for years. Eventually got some Diorshow mascara. It is awful. I was so disappointed I was actually really cross at the prices they dare charge for it when it is massively inferior to most other brands I've ever tried.
It flaked and smudged worse than any other mascara and I've tried lots,
ranging from Rimmel to Lancôme and all prices in between.
I really would avoid it if I were you!
Sorry that turned into a bit of a rant
but its probably my worst beauty buy ever.
