My usually mascara is the DiorShow Blackout mascara!
I really liked this mascara and it did a good job lengthening and separating my lashes! Almost better than the Dior mascara!
The DiorShow mascara tends to cost your lashes and makes them dark and long, but thus perversion mascara separates each lash!
Here is a comparison of the brushes from each mascara, DiorShoe Blackout (left) and Perversion (right). The Urban Decay mascara wand has several bristles that separates and coats!
