For those of you visiting my page for this reason, yes I was the Ellie at Megacon 2013.
The costume was a collaboration between myself and a good friend who cosplayed Moxxi. I have never cosplayed before, really, nor made such a time consuming costume. Moxxi on the other hand is very experienced and was vital in making this suit become a reality. When we get more pictures, I will post them here and she will be sharing on her cosplay.com page.
The blood, sweat(LOTS of sweat), and tears were all worth it. Thank you everyone for all the love and support. If you have any questions I'm happy to answer them.
