It seems like you have a problem with the accuracy of the set, to be completely honest, man.
You might be right.
Like it or not, it was 1985, and Marty was rocking some mom jeans:
You don't have this in-hand yet right? You might be surprised by how tightly these pants taper at the bottom. I was hoping that it was just the wider angle of most of the pics in this thread, but they are really tight at the bottom. Like skinny jeans tight.
The extreme taper, plus the high waist, plus the stone wash really make me think "mom jeans". In a way that the above picture doesn't.
To be clear, I admit this might just be me.
And the elastic on the bottom of the jacket was rather tight, pulling the bottom edges outward.
The way the jacket is hanging in the above pic would be impossible with the 1/6 jacket. The elastic very aggressively pulls the bottom of the jacket back. Again, let me know what you think when you have it in-hand.
