...dress up as PSY for Halloween? Grab some round, black sunglasses, find a colorful tux at a thrift shop, slick back your hair and learn the dance (if you haven't already).
...dress up as Theresa Caputo, the Long Island Medium? Don the most gigantic faux nails you can find, grab a blonde wig and tease it high to the sky, practice a Long Island accent and learn her "reading" style.
...transform yourself into Bea Arthur? Grab a caftan/muu muu/house dress, add some plastic beads or a boa and an old lady wig and you'll be set. Switch the grey wig for red, ditch the boa and add a colorful cat eye to become Endora from Bewitched.
Don't worry - there's still time to pull a fun and easy costume together before Halloween!
