Personally, I can't see wearing the same outfit the next day. She had a closet full of clothes, I can't believe she'd want to put on the same clothes she'd worn the night before.
True, after wearing in only a few hours it wouldn't have been as raunchy as if she'd worn it the entire day, but I know from just having gone through Christmas socializing that plenty can happen to make an outfit less then fresh in a few hours.
I don't know about others, but when I'm dressed in a long-sleeved shirt with a jacket type garment over it inside someone's house, I end up perspiring - especially when I'm talking and laughing and moving around, having a good time. That alone would have me not wanting to dress in the same clothes the next day, and add into that the atmosphere - were people smoking in the White's house during the party? I'm not a smoker, and when I realize I've been around smokers enough for the smell to have gotten on my clothes, I change those clothes. Patsy was a former smoker. Perhaps the smoke smell, if there was any, didn't bother her.
But flying to Michigan...being on a plane for more than an hour in an outfit that may smell of smoke or perspiration would be more than I could handle, not to mention I don't think it would be as comfortable as, say, jeans and sweatshirt. Patsy was also going to spending time with Melinda's fiancé, Stewart Long, someone she barely knew. I'd be surprised if Patsy was all set to wow the new beau in an outfit she'd had on the night before as well as on the flight up to Michigan. I just don't think it fits in with who her friends say she was - her own friends expressed disbelief that Patsy would get up and redress in the same outfit she'd worn the night before. it wasn't like she didn't have any other Christmas-y outfit she could have worn....
And then there's the fiber evidence. The fibers found in the paint tray, on the tape, and tied into the ligature knot were chemically and microscopically consistent with Patsy's jacket, which leads me to believe that she had that jacket on when she staged the scene, with the tape and tying the ligature around JB's neck. That makes me wonder...how likely is it that she'd be doing all of that still in her jacket? I've never staged a crime scene and killed a child, but I'm pretty sure I'd make myself comfortable and shed off the jacket before I rolled up my sleeves to do the dirty work. I sure as heck would not be standing there in the same outfit I'd had on all night when the police arrived.
So what's the real story in regards to the jacket and Patsy wearing it two days in a row?
