I disagree. There’s nothing acceptable about going out wearing a NASCAR jacket.
What if it has tails and shiny lapels?
I wanted to add here that I’m also 30 years old, and last night I watched Superman Returns while wearing Superman pajamas, because I’m just that much of a geek. And if they sold queen-sized Superman sheets, I’d have slept on them immediately after. 
And I’m a girl.
I will agree that maybe it wasn’t necessary to mention the jammies in the headline of the obit, but as middleman said, the writer wouldn’t have known unless somebody told him. If I die in Superman pajamas, I want it included in my obit.
I smell the stink of a journalist who thought the story was beneath him.
See, but that makes all the difference. “30-year old chick in Superman PJs” ranges anywhere from “cute” to “hot”. “30-year old dude…”, well, not so much.
I did think the tone of the obit was a bit condescending. It could be taken any number of ways (and I’m assuming it was simply a manifestation of his love for the medium), but any journalist is going to know the way it would be taken by any non-comic book fan (that is, a majority of the population). A bit of a low-blow, gratutious without being insightful.
RIP, though. 
Reporters don’t generally do titles. It was probably done by someone at CNN.
I would have written the lede sort of like this:
"Showing to the end his love for his life’s work, comic book illustrator Dave Cockrum was wearing his Superman pajamas and covered in his Batman blanket when he died Sunday. "
Same factual piece of information, with a positive spin.
The headline I probably would have reworked into something like “X-men illustrator passes away in superhero style”.
Not bad, and it does eliminate the condescension - but then again, “show, don’t tell”- and I think it’s a better lead with a little mystery to it. If my reporter gave me that sentences, I probably would have chopped off the beginning. I’d rather give the reader and picture with some mystery than start explaining the image in the first sentence.
Wow, that’s sad. I really liked his work on X Men.

I will never forget finding issue #95 in the local store when I was around 12 ("Not a hoax! Not a dream! In this issue, an X-Man dies!!!). That started a love affair I had with the title for a few years - I went back and got many of the old issues - Neal Adams’ Sentinal run, for example - but always felt that Claremont/Cockrum were pretty much it.
RIP, Dave and I hope you wore your jammies with pride - you done good.
I’m not a BIG comics fan, I had no idea who Dave Cockrum was until just now, and I was really touched about his gesture of love for the artform at his death.
And dammit, now you made me laugh.
How about if you’re wearing someone else’s Superman pajamas? And what if you were wearing, say, Wonder Woman underoos (as I occasionally have been known to do)?
I, um … I actually also have Wonder Woman jammies. If only they made underoos to fit my fat ass, I’d be ecstatic.
I never said they fit – I just wear 'em anyway.
