Missing Legs !

What im missing mesh texture ? and how it comes ?

I believe that can occur if the game is telling an object to equip to a certain slot (in this case I would guess the calf slot) but the bsdismember of the mesh itself is telling it to equip to a different slot.  Since you're in Bleakfalls Barrow, I'm assuming you're starting a new game?  I'll give the standard advice: run Loot and try disabling any mods you may have just installed.
