There is what some may call the granny pantie - gives that full coverage support, no strong elasticity - primo comfort! Not ideally worn with spandex
The boy shorts - teenage like, thicker material and usually has something like "juicy" or "all star" stiched on it.
The thong - shows no pantie line through clothes...sometimes, but somehow makes its way to the outside world when someone bends over.
Bikini - an altered and more modern granny pantie. does comfort and support but you get that sexy feeling with the thinner side strings
And then there is always the option to go comando. We just all pray its not a windy day if you're attire is a short spring dress!
