(Respectfully snipped)
I don't see why the long johns are such a big deal. They're interesting for sure but could easily be nothing. We already knew JB wore B's hand-me-downs so it's not surprising they'd be in her pajama drawer (which is where all the old, comfy, not wearable in public clothes go in my experience). No, it doesn't track with the pageant queen image but I'm not going to discount PDI or JDI (or BDI and J or P staged) because she wasn't staged in something girly and nice. Besides the huge urine stain that obviously came post-mortem they appear to be clean. If that's something JB would usually wear to bed it may not have occurred to the stager that others would find it weird for her to be wearing them. We never even knew she was wearing boy's long johns until a few weeks ago, no one saw a reason to comment on it, not even Kolar.
As for the underpants, it could be she was dressed in overly large underpants by a young boy who wouldn't think about how strange it would look. And yet he went through the trouble of tracking down a brand new clean pair of underwear fresh out if the package for some reason? A new package that wasn't ever found by police - did he hide it? And either by accident or thanks to a keen eye for detail, he puts her in Wednesday underpants to match the last day she was alive, as if to indicate she was wearing them all that day, as Patsy tried to make the police believe. IDK, I think there's more to the big Bloomies than carelessness.
