“I can’t wear your mother’s clothes”

PARIS: I can’t wear your mother’s clothes.
RORY: Yes you can, I do it all the time.

Surely the reason Paris can’t wear Lorelai’s clothes is that they are different heights – Liza Weil is about 5 inches shorter than Lauren Graham. Oddly enough, Rory gives Paris one of Lorelai’s mini dresses to wear, and it is very short on Paris as well, even though when a short person borrows a tall person’s clothes they will inevitably be a lot longer on them.
