Ah, OK, the visible neon strips are deforming; yes that should be avoided. Perhaps select the neon strips, make them a separate object in the modeler, and subdivide them? Maybe better, if you could select the edges running parallel with the limb/torso, and cut those edges,increasing the poly density along that long axis, making the neon strips more foldable, at lesser cost in polygon increase?

The neon doesn't need to be welded to the main fabric for a conforming figure, nor does it need to be welded for dynamic use if you assign everything to "constrained" (not "dynamic"). By the way, the demo image I made used the suit as dynamic, with all vertices/polys put in the constrained group, same for the emitter, and it seemed to work just fine.
