Let there be no argument. This is the only Princess Leia costume that matters. From The Return of the Jedi. Slave Leia. If you say you’re going to a Halloween party dressed as Princess Leia and show up in some Ewok village outfit, they will ask you to leave. Think that might be a Federal Law. Not sure. So, let’s talk about the costume here. First? It’s pretty damn awesome. Instagram star Devon Jenelle did the galaxy a favor when she posted this clip to her YouTube. Think we all agree she looks smashing. So, ladies, if you were ever wondering if you should get a Princess Leia costume, the answer is yes. And we highly suggest you get this one. Happy Halloween!
