So, Argonian tails clip through everything. Okay, fine I guess- at least with pants. However, there are a few Argonian specific styles, specifically with kilts. I'm sure the idea with those kilts is to facilitate a tail slipping easily under and out from it, whilst remaining modestly covered. However, the tail clips through the kilts too. It would look a lot better if at least those few specific kilts could be re-modelled with their tail in mind, so it rests over the tail.
There are only a handful of motifs from Argonian dungeons, Murkmire and whatever might be coming with Blackwood, as well as a few costumes that would need this fix. This being an Argonian-ish dlc, this would be the time.
