Attire: Whatever you want (Aaron will rock a bow tie, but Lawrence will probably be in a hoodie sweatshirt. Choose your poison).
Also announcing the "First Annual DoubleDutch Ugly Christmas Sweater Contest." To enter a photo to for consideration, post it on the event wall. Voting will happen live at the event. (Note: You don't need to wear your ugly christmas sweater to the party -- a photo will suffice. That is, unless you want to.)
