A general rule of thumb when picking out a mascara wand: how the wand looks is how it's going to apply. A fat and fluffy brush will yield voluminous, fat and fluffy lashes. Getting larger-than-life volume and thickness is the most common look that women are after, says Vickery. So to pump up wimpy lashes, pick either a twisted wire brush or plastic bristle brush that is big and fat.

"For uniform, very defined separation and length, a comb may be your best tool," says Vickery. But you can also get length and definition with smaller brushes -- just look for ones that are plastic or rubber with closely spaced bristles. Ball shaped brushes also allow you to get extreme definition because the smaller shape allows you to get from root to tip, and to evenly coat each and every lash individually.

For a winged lash look, choose a brush that mirrors the effect you're going for. "When people think about curl, curved brushes are what they think about," says Vickery. You can also try one that looks like an hourglass &mdash: the shape gives you the lift and curl of a curved brush while also getting to every last lash.

Okay, so you want it all. Why not create your own mascara cocktail (the process of layering two or more types of mascara to your lashes)? Apparently I am late to this party, as nearly everyone in the office has mixed and matched their mascaras at some point. CoverGirl's Bombshell Volume mascara was partially inspired by women who like to combine mascaras. One side of the mascara is a volumizing formula and brush, while the other side is a thinner topcoat that, through the use of a different brush, adds intensity and depth of color.

And Buxom Amplified Lash Mascara is expandable -- when it is extended the spaced out bristles will give you volume, and when you collapse it the bristles move closer together to lift and separate your lashes.
