Socks and Leggings invisible with certain pants

Greetings,

In cas and live mode you can see .... " nothing"  ...

Wearing this pants, the socks and the leggins become invisible :  the one is a skin-tight basegame pant with floral pattern, the other ia a normal one from the magical-dlc, uni-colored or with stribes, and big buttons both sides of the front, tight too.

I am sorry : i can not send you pictures.
