Cosplayer Eva Keck totally nails it with her Dr. Chakwas cosplay from Mass Effect 2. Photo by David “DTJAAAAM” Ngo at DragonCon 2013. The GIF is from this Reddit post (larger sizes available). Nice Work!
P.S. Next time I play the ME2 suicide mission I will send an escort with Chakwas and her group so they won’t all get slaughtered. Just saying.
