Im looking for a story I beleive it was here a LONG time ago but haven't had any luck tracking it down.
It was a halloween based story about a girl who buys a zombie costume and wears it. When she goes to take it off its fused to her and cant be removed. I beleive I remember at the end her boyfriend makes her a suit that looks like she used to so she could live a semi normal life.
I'd start with this search (https://grometsplaza.net/search.html?site=17&con=transform!stuck), but sounds like https://grometsplaza.net/special/halloween08/heathers_halloweenhell.html might be your story?
