Sooo here it is!
I have found Jennifer's vest! It is 95% accurate. The only thing that is different from what I can see is that the pockets have a square pattern, while mine are diamonds.
But that leads me to believe that the vest might indeed have been made by Guess George Marciano and it was not just something re imagined by the costume department!
I took these pictures with the flash, but it is a bit more faded, the labels are also quite faded, sadly there are no way to know the model number...
