|Most Portal cosplayers decide to cosplay as Chell. But being male makes it a bit different, thus I've decided to be a different Portal test subject.|
We saw from Portal 2's multiplayer ending that Aperture did infact have male test subjects as well as women, so that's no problem.
The overall costume is the same as Chell's in Portal 2, with the exeption of the tank-top and long fall boots.
Instead I've opted for an Aperture Labs T-shirt underneath the overalls, and designed a "men's version" of the Aperture Science Long-fall boot.
