Well if you cant unequip you cant repair it. The only way I can think of is to weave another one and replace it. Anyone else got any other methods?? I really hate seeing the yellow equipment need repair icon.
no other way we know of, just gotta have some spare undies to wear while you repair your others. An unfortunate waste of inventory space! if they are going to make undies un-removable they should either make them indestructible, or able to be repaired on the body.
