100% Cotton so it SHRINKS!  Lost several inches off bottom.  Fortunately, not too much so it still looks OK and now sits just above the bottom floor molding strip -- which is OK.  Other than that, I like it!  The colors work for me.  Works for a Man's bathroom -- so it is fine.  It is the best looking shower curtain I've found so far.  (I've gone through quite a few trying to find one that works.)  This one works!  It fits.  It is great!  I'm happy (for now).  Thanks!
