Plan B underwear 

The underwear at the bottom of your drawer that has long ago stopped fitting and is occasionally used when on menstrual cylcle, but will be used when all other panties are dirty. Honestly most people dont know why they even own them, but never thrown away.

The reason why im wearing granny panties today is because I had to resort to my plan B underwear.
