I am sure that this is a fantasy-thing for the big majority as it seems?
Guess I am one of the few who actually like the heroine to wear a (sexy) bra and panties underneath. And yeah that counts for the "normal" women as well.
Not so easy to explain why....but I think I like the "added" layer which leaves more mystery and more to unpack...if you know what I mean.
And also I would say that a heroine who fights crime and doesn't wear any underwear would be a ...slut

Perhaps that is actually what many folks want to see?
Besides ....wearing no underwear would have countless negative effects (hygiene, hanging boobs in the long run, cold weather....) but ok that's me thinking too practical I guess.
