The subtleties of the size-12's are many, not many get them.
The police never realized the importance of the size-12's until well after the autopsy, when they returned looking for the rest of JonBenet's underwear.
Sure JonBenet might have worn anything other, or none, than a Wednesday size-6 pair. That is an inference not based on anything, we know Patsy purchased Bloomingdales size-12 as a gift for her niece Jenny, but what did she buy for JonBenet, size-6 or size-12, if it was size-12 then there should be two packs of Bloomingdales size-12 in the house, there were none! So again what size did she purchase for JonBenet, read the transcript below at your leisure.
Patsy Interview Atlanta 2000, Excerpt
Since the investigators are asking about the Bloomingdales purchased by Patsy then presumably these are size-6, furthermore you can infer the Wednesday pair might be missing, hence Patsy's sudden onset of amnesia when asked about what she purchased for JonBenet!
I agree, and no parent is going to redress their child in oversized underwear, only at a staged crime-scene might someone think We must have a Wednesday pair, since thats what she was wearing,, since in nearly every other scenario size and day of the week are irrelevant, or can be explained away, i.e. size-12's were not used because she had already been wearing size-12's!
ETA: note from the interview JonBenet selects her underwear, and that if Patsy had redressed JonBenet in the size-12's, she would make sure they really were placed into her underwear drawer!
