Dynamic clothing props generally don't have morphs, so basically you need to have the character in zeroed position without morphs in first frame.

Then you can apply morphs for the char in frame 5, 10 or 15 and apply the final pose in frame 30.

Set the steps per frame high enough so the pose/morph change is not too high between calculationsteps.

You need also avoid figures parts touching each other or going inside each other if there's cloth between them. Like arm going inside torso because it will explode the dynamic clothing mesh.

you can set the animation lenght higher and set the next pose at frame 45 or whatever suits your purpose so you can chain the poses and do it all in 1 calculation.

You're not telling if you are doing stills or animation.

There's a button in cloth room to set figures (and bodyparts) to collide with.

If you have more than 1 dynamic clothing prop you need to do separate simulations for each of them.

Most of the time setting up dynamic clothing is by trial and error to get it the way you want. Atleast for me it is.
