Good for you. Socializing through such ways is a great way to enjoy your time. And besides, I am not Star Wars fan and have not watched any of the movie series
I am planning to go to a movie themed costume part this coming weekend. I bought all my gear weeks in advance. I'll be dressed up as Darth Vader.
