What are you favorite undies, and why?

I live in a fantasy world where bras and undies always come in lovely rich colours and match each other, however the harsh reality is beige cotton granny numbers. Which I actually love because they are comfy.

But I hear that some brave souls wear g-strings and little skimpy bitty things all the time. What I wanna know is - how you do even FIND them after you have put them on .
