The kilt without the chainmail would be kinda easy to do. First take that chainmail which has that belt with shoulder strap and blue tunic under it (I think it is Chain Hauberk). Then you overwrite that chainmail part with some sort of skin thingie, the place the kilt on to it. Voíla!
(I am no good at texturing so YOU try it, I just figured it out one night. If someone try this (I hope someone do!) I take no responsebility if game crashes 'till end of days
