Fitting two dynamic clothing items in the Cloth Room requires 2 separate simulations, 1 for each item.  If there is an overlap of clothing layers then you need to make adjustments for each item to properly collide and drape over themselves.  Otherwise, the simulation will freeze and crash.  That shatter effect is from an unusual collision with something in the scene.  

You haven't provided enough information about your scene setup.  What items are you loading onto the stage?  Are the items fitting correctly before your simulation?  We can't tell from the screencap.  BTW, if you want to see if the clothing fits 360 degrees, select your figure (LF2) and spin the yRotation dial.
