i lack skills such 3d etc. so here i would give only suggestion as i am unable to do such mod by myself.
i would like to see a skirt as pants, i got that idea when i was checking dust coat for my char. it looks very good there, unfortunately wearing coat and any other armor does not look good. so adding a skirt looking similar to lower part of coat, would be awesome. change slot for belt and then char can wear normal pants + skirt.
also ninja outfit has such mask like emmmm ninja
but there is no such thing as stand alone cloth. so if someone has such skills and want to try, i encourage him to do so.regards.
