RTF is a global modification that replaces all towns in the game.

Is the dark green cloth supposed to be a "skirt," that infamous "shameful cloth"? It just seems strange that the leg goes through it on the left side.

This is because the same texture is used both inside and outside. There are no shadows to distinguish what's where, and everything blends together. However, it could be made like the skeletons in the sixth game – a full skirt with an additional vertical strip in the front. I think that was a reference to Egyptian clothing.
