What is the context of this?

I do admit, I have an irrational urge to go to 7-11 now after seeing Uzuki in that transparent shopping bag swimsuit.

Western media seems to think it's a fashion trend.

It started a few weeks ago in Taiwan.

Teddy Captain and Belle Xie seem to have started it by posting pictures of themselves wearing nothing but plastic bags on social media and it exploded from there.
