SGC - It does pretty much both, it gives the really dramatic falsh lash effect, depending on the amount of strokes. If u want uber glam, keep coating the lashes... and it never seems to clump!
I've tried pretty much every mascara. I have naturally long lashes and could never find a mascara that enhances what i already have (without making my lashes look like spider legs). Dior is by far the best.
Update: I cannot smell any rosewater in the DiorShow, is it made differently in the US?
