Wearing PJs in Public?

Let it be known that I am firmly in the camp with those who believe that the casualization of clothing in the U.S. in the late-20th & early-21st centuries is the first step to the downfall of our civilization & that wearing pajamas in public is a sure sign of the coming apocalypse.

I feel that people are allowed to wear PJs outside the home exactly three times in their lives: (1) once when you have the flu & need to make a trip to the drugstore for tissues & meds, (2) once when you're miserably depressed & need chocolate &/or booze between the hours of 2am and 6am, & (3) one additional time to be used judiciously, carefully, not in broad daylight or among more than a dozen people, & it can only last for no more than 10 minutes.

However, if you can wear something as comfy as PJs without looking like it, rock on with your bad self.

And the later is precisely what I attempted to do -- successfully, I hope! -- in this outfit. I wore this combo (which is a clear riff on this jeans-based outfit) to go hangout at my girlfriend's house a couple weekends ago. I ran a shopping errand first, so I was seen in public too. While the ensemble is quite casual, I feel that it qualifies as presentable, non-sleepwear clothing. What do you think?

What I'm wearing:
Black crochet duster, Coldwater Creek
Burgundy knit cowl-neck top, Forever 21
Black long-sleeve knit top, Old Navy
Wide black knit pants, Target
Embellished black flats, unknown brand
Black & gold medallion earrings, Forever 21

How casual do you go in public?
