Sue Sylvester from "Glee"

"Abrasive" is probably an understatement to describe Sue Sylvester from "Glee." No one can ever get tired of this gym teacher's screaming insults through her ever-present megaphone. Having an excuse to be mean is the best way to spend Halloween. This is a new take on your old witch costume go-to.

Get her look: Jennings says actress Jane Lynch clearly has never done Botox as she is chock full of expressions. Her furrowed brows and laugh lines are a must-do with this look. Using a similar technique for the Betty White costume, if you're younger than your 40s, you want to age your face. Jennings also says Lynch doesn't have the smoothest of skin. To manipulate her skin tone, try "Wrinkle Stipple," a wrinkling agent you can find at most costume stores. Then stipple foundation right over it. Do this all over your face. Use minimal makeup, and top the look off with a shaggy blonde boycut wig, an Adidas tracksuit and a megaphone.
