Chell from Portal 2
My very first cosplay <3 The one that started it all. In every interview where they ask me how I got into cosplay I must bring up this cosplay. I had just fallen in love with the game (very late to the party) and Needed a portal gun to decorate my living room. That was back in the days before Valve produced their own replica. One thing led to another and I found mentions of a norwegian con and thought hey, let's make the whole Chell outfit and bring my Gun. And I had the best time, it is still my best con experience.
