Warning: If you decide to go as Annie Hall for Halloween, be prepared to get asked if you are Ellen, Rachel Maddow, Don Draper, or a recently transgendered teen on prom night multiple times over the course of the evening with no one at all guessing Annie Hall despite your nearly perfect costume.
(Not exactly a great pic of my costume, but it’s all I’ve got. And you can see the tie and vest, which are the main sellers anyway.)
