I love the subject of dynamic clothes. These type of clothes make more sense in all aspect, such as naturally flowing, like in when you have a character move from one point at frame 0 to another point at a later frame, it gives the wind effect. I doubt Poser has any "wind" option as I've searched (I have Poser 9). It depends how fast and far he/she moves. Also long dresses resting on the floor (if you have the floor included in "Collide against").

As for the "default breast morphs" in dynamic clothes, I do understand what you're saying, that the "extra length" of the clothes will look odd. When I started playing with dynamic clothes in Poser and got into the subject a few years back, someone said "shrink V4 to a smaller percentage at frame 0 and reset the percent at frame 5 and you get a tight fit". I thought about that and thought, "well that should work with characters with small breasts then", so I played. One thing about it, the shirt, for example, looks smaller on the character cause it shrinks. So what I do is increase the length of the shirt itself so it doesn't ride up on her belly and look like a half shirt. There's a lot of pros as to how I work, but indeed there's still a bit of con. If dynamic clothes came with small breasts, it would work quite better. I bought a K4 pack and when I use the T-shirt on V4 with small breasts, or a V4 child (as you can see in my store), then it works perfect. Just gotta re-size the shirt itself. Another off topic, for a tighter fit... first, I set the "collision offset" and "collision depth" (in Collide against option) to 0.500 which is highly recommended by others. But it isn't really the tightest. Setting them lower has a bit of problem (I forgot what though, it's been so long since I played with those settings). So after I let the clothes similate, I set it's size to 98% instead of 100% and it gives a much tighter look without poke throughs (at least 90% of times).

Copy and pasting character morphs to static clothes, I recognize that. I think Daz Studio 4 had that... but maybe only from character to character. Anyways, Poser 9 doesn't have that, so when I upgrade Poser, I'll sure be playing with that, sounds interesting!

Here's a sample of the dynamic clothe on a young character, picture below.
