Halloween costume 2008, Dr. Liara T'Soni from Mass Effect (1). My first attempt at working with latex - I later wrote a little tutorial on how to make a latex headpiece, based on my experiences. This picture is of my third latex headpiece and a really, really bad makeup job - I didn't feel like sitting 4 hours for makeup, so you will have to excuse the blotchy blue and my (lack of) photoshop skills.
Rest of the images can be seen here
And you can find the complete headpiece tutorial here
