i have to agree.  it's a crap shoot and occasional p.i.t.a to clothify an item that hasn't been designed to be dynamic.  that's where i've had things take forever or behave problematically.  but since i'm going against the instructed use, i'm more surprised when it goes well than otherwise.  most clothes i've had that were designed to be dynamic has worked beautifully, because all the settings were already in place.

these are the issues i've run into with making conforming clothes dynamic, so i'm guessing they sort of hold for what i'd like in dynamic products:

full skirts or other such items flared into a circle at default.  to get both xena's hope gear and lady littlefox's oriental fantasy to behave drape properly in my chosen poses, had to use 4 magnets to flare out the skirts.  on the oriental fantasy outfit i had to flare and raise the sleeves.    basically, where draped items fall from matters a great deal, and for maximum flexibility, it seems  to me in my very limited experience, that it's works better for draped items to fall into the pose rather than start from a more fitted pose.

if there are important features, please make a specific material for them.  that way they can be constrained more, and kept from distorting.  frankly, this would be helpful in general.  i find it equally frustrating to find that a modeled detail has no separate material for me to customize (m3 marauders, a great set, disappointed me in this one respect).  even though hope gear's stripes weren't modeled, they're highly integral to the look of the set.  in this case, i ought to learn to make them a separate material and group.   that is to say, if i want it to work differently, i should change it myself, since it was never meant to be dynamic.  but it would be great if fine details like trim could be handled separately in general. 

and please couple it with lots of detail.  svdl's set is a  perfect example.  the lack of detail coupled with my penchant for action gear has kept me from buying most dynamic sets.  though the stiffness of some sets, especially fantasy ones, has kept me from doing more than trying out several conforming sets.
