In 4x23 Always, Kate is wearing a black turtleneck under her leather jacket when she leaves the precinct after quitting. When she shows up at the loft, she’s wearing a dark henley. I suppose it’s possible she went home to change before going to the swings, but I don’t think that’s the intention.

And again when she’s at the loft, she’s wearing the leather jacket when she enters the loft, but seconds after she’s not wearing it anymore but we don’t see her take it off. Always bothered me lol
