i dont think she was awakened under unusual circumstances. i think she stated she got fully dressed before she noticed jon benet missing.
it may well be that Patsy Ramsey had been fully dressed before she realized Jon Benet was missing ... I really never followed the case that closely.
But as to the clothing, more than once, especially during the holidays or vacation, I will throw on the same thing in the morning that I'd worn the night before, then eventually get dressed for the new day. The only guilt that would associate with is being lazy, and that's not all bad.
From that weak thread, I would never accuse anyone of murder, much less the murder of their own child.
