Cycling panties, yay or nay?

I forget the brand, but I have a padded pair of underwear that I got years ago from REI. It isn't the one linked above. I wear them sometimes to spin class. I've never had a problem with chafing. I think for a ride less than an hour, which I guess most commutes are, they would be fine, if you need padding for a ride that short. As long as the chamois is removable for the day, or you bring an extra pair of undies anyway, they should be fine. They certainly are more attractive than the pair I have, or any of my underwear, for that matter!

I tend to wear the liner shorts for short errand rides. I cannot sit on a bike without a chamois. Even the liner shorts don't work that well for rides over 5 miles. And, my regular shorts are not super padded (Terry Bellas and Sugoi).
I bought a pair of padded underpants from TE quite a few years ago. They were huge granny panties; there was no x small so I got smalls (my azz is not that petite). They went in the trash after a few attempts at riding in them.
When I commuted (13.8 miles), I wore regular cycling clothes.
