I'm a cheeky boy shorts kind of girl with thongs a close second, but when it comes to other girls I go wild over plain white cotton bikinis (the same goes for guys in white briefs).  

boy shorts for dates, or no panties. I love the way boy shorts look on girls and guys I like boxer briefs

Boy shorts or commando!

of several providers re what they liked on men. Majority said boxer briefs, some said bikinis (if he's got the bod for it), and some said it didn't matter (envelope talking?). None said white briefs... which I was glad to hear as I stopped wearing those when I was in high school.  

Only on women, of course.

I hate wearing panties in daily life, too confining. I love undressing others to discover they're knickerless too.

....I am more interested in the boob packaging versus south of the border.  Wrap those puppies up in something inviting that I can remove without and instruction manual, and I am a happy campler.

Plus you can get right into it on a date with no delays. Lol

Yes usually commando but a tiny thong with skirts and dresses

Of course, they didn't start off crotchless.  It takes a few months.

But if she walks anywhere for more that 3 minutes, the sweat starts flowing.  I don't know what it is about no panties that makes the crotch so damn sweaty!  I guess underwear absorbs more than we think

Lush makes an awesome one, "Silky Underwear".

Now to get the horrible image out of your mind, it wasn't me in the sundress, no panties!
It was my female companions

Bikini panties but with a garter belt & stockings, nothing sexier.  Guess I spent to many of my formative years watching 70's porn.  I think it's amazing I can perform without saxophone music playing.
