I absolutely love dyanamic clothing!  And I can see some merit behind using it for a bikini or male and female under garments.

If you look at even the tightest of panties from behind, they do tend to crinkle a bit when the person is walking. So if you are looking for extreme realism in your images so far as clothing goes, then dynamic clothing will go along way to help you with that goal.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
