I picture Garak wearing boxers. Something silky that feels good against his skin.

Denny looks like a commando man, or either a cotton boxer person.

HP fandom? Hmm.. Never really thought about it before. I can see McGonnagal wearing something old fashioned, just because of her age, though. I wonder if they can buy undergarments at the same place they buy their robes? lol *down plot bunny, down!*
