Sweater, Shawl or Shrug for bridal party???

My wedding is in January and I am trying to figure out what to have my girls wear over their shoulders. I would like to purchase it for them. I was thinking of something other than a mathcing shawl this way they can use it again. Any suggestions?
Here is pic of the dress(I can't find a real pic of the dress so I photoshopped it). Thanks!

OK That pic is really small. It is in my album.
