Ever since Disney bought Star Wars there has been quite a lot of Disney/Star Wars mash up costumes done. This was my favorite pair and especially Merida's lightbow was amazing up close.
There are also the fun/humorous costumes, like this Bothan Walking around the floor.
For the Running of the Hoods, the humans were also joined by a Jawa and a wookiee.
That must have been so hot to run around in.
One of the best costumes was this Jawa with BB-8 though.
It's actually an adult, with the head in the BB-8 dome, but it looked like the Jawa was carrying him around. Both the Jawa costume and BB-8 was really well done and together it was perfect.
My favorite costume of the weekend was this really handsome Bail Organa. Yes, I am a total Bail Organa fangirl, and just seeing this costume made me happy, but then I almost died when he had the rest of his family with him.
