Awww... Lydia.  The wild child in the Bennet family.  I had to pick something outrageous for her to wear.  The longer I look at this outfit, the more I am reminded of Minnie Mouse, but that's okay.  Somehow I think Lydia would approve.  As a side note, I would actually wear more of this outfit, just not all together.
