Party Pumpkin

Pumpkin-hued polishes more sassy than sweet? Orly's Right Amount of Evil ($10) adds a hint of sparkle or an all-out disco ball of shine, depending how thick you coat your nails. R.I.P. ($10), also from Orly, leaves a midnight black coat underneath chunky orange glitter.
Black Magic

Just how dark do you want to go? For moms dashing out to a holiday party, one coat of Chanel's Le Vernis Black Satin ($26) will add smolder without the extra wait. For a slightly lighter black, try Butter London's Union Jack Black ($14). Feeling the glitter? Butter London's Gobsmacked ($14) adds a sparkly gray topcoat over any spooky shade. Layer it on thick for a wicked veil of metallic color.

Bloody Good Time

Adding some extra vamp to your Halloween duds is easy with these sanguineous shades. Inspired by HBO's vampire series True Blood, Deborah Lippmann's Let It Bleed ($25), from her Forsaken Lip & Nail Duet. Chanel's Malice and Butter London's La Moss ($14) will blend in with your glass of pinot noir.
Ghost of a Chance

If you'd rather ditch the dark stuff in favor of a whiter shade of pale or even flesh tone, Deborah Lippmann's limited-edition Fairydust (paired with the zombie-hued Human Nature in the Sookie Sookie pack, $30) is ghostly white with a flash of red shimmer. Lippmann's New Flesh (part of the above Bad Things Pack mini trio, $25) will have Halloween revelers wondering where skin ends and nails begin.
