Quickly dressing, she picked Isileth from the stand on her 

dresser

and slipped her in her jacket.

    How long IS this sword?  How big is that _jacket_??


I've seen this question several times.  I'm not exactly sure how it 
could be done, but I know it could be done.  How do I know?  Watch 
the first "Highlander" movie.  The Highlander is at a WWF (I think) 
match and he is challenged by another Immortal.  He pulls the Katana 
from out of his jacket.  It would take some very careful tailoring, 
but it could be done.
