What problem do you have there draping sleeves then? Inclined arms works great for me. 

In fact my problem is not the draping in MD, but the application to Poser figures. 

Workflow:

• export .obj with lowered arms shape from MD (I do not want wrinkled shoulders and normal proportions of textureson the shoulder)

• load .obj in Poser, in setuproom inject the rigging rig made to suit the MD avatar (or lowered arm version of Poser figure if I used that in MD. Carrier figures are just body and main limbs,hand.feet. No fingers, toes, head features.

• in Pose room pose the cloth-figure in a pose to suit my target figure (T-pose, arms bend, legs position), tweak joints when necessary for good shape. Texture on shoulders of clothing look horrible of course, but UV's are preserved

•  in fitting room convert clothing to target figure.

• when posed to natural 'arms down' position the texture on the shoulders returns to more or less original proportions. 

So with T-posed figures I need to do an extra setup room session and can only hope the deformations induced in the bending to T-pose are reversed well when the clothing is bend to a pose in which the fabric should be neither stretched or wrinkled. 

If the 'arms low' pose would be the default, the .obj could go tot he fitting room directly.
