This is the part that confused me:
"So, at least two packages of different sized Bloomies were bought. The cousin was considerably older than JonBenet with a larger Bloomies-appropriate body part. (Evidently, a bigger butt. I guess she's an adult now and I can say that!)
When they got them home, the cousin's package was put away for Christmas wrapping later (presumably in the basement where all the FAO presents were stored, too)."
So, it sounds like, there WERE two packages, totaling 14 underwear, somewhere in the house? If the cousins package was in the basement then we have a package from both the bedroom area and the basement from which these gigantic bloomies she was wearing could have come from?
*Could have* but Patsy told a different story.
