Spikes & Safety Pins and still more fashion than punk

I am utterly intrigued by the clever use of safety pins on this coat. I assume it's a DIY but perhaps it came that way. Ditto the spikes on the bag. She's like the quirky goth niece of Lynn Yaeger.
*and mini-update: I've been made aware that Lady Gaga modified a Birkin bag with spikes....so perhaps this is copying that? Or maybe she's as ignorant of the minutiae of pop culture as I am and came up with it herself...
