Want to look as good as that guy in the picture? WISHFUL THINKING. This is the Star Wars Schematics Hawaiian Shirt available from ThinkGeek ($50). It makes the perfect casual Friday shirt to let your coworkers know you like Hawaiian shirts, Star Wars, and respect HR's decision that only wearing boxer briefs was a little too casual last Friday.
Thanks to LL, who agrees the best thing about casual Fridays isn't what you get to wear, it's sneaking out after lunch and starting your weekend early.
