Wizard teleport scrolls

That's an entirely different issue, though. And, if you've already cast the spell, your state of nakedness or not doesn't matter. As long as you had the robes on when you opened the box, the important part of the spell was cast when you were fully clothed. You're just completing the spell after somebody's toolboxed your head in and stripped you naked. That's how magic works.
