The only thing that comes to mind is a story I read a while back about a girl putting on her mom's jeans and bragging about how good they looked on her. So her mom set about fattening her up, while simultaneously going on a diet to reverse the situation. I can't recall where to find the story, but it was something like, "Mom's Jeans" or something.... god I have no clue where it is anymore or what the name of it was....
It's a really weirdly rare story for something I think is probably a really common trope and there should be more of.
