When the individual chicken clothes were still public, I put them on (even though they made me bald and naked at the time... :/ and saved it) and then the costume was removed, but I still wore it. When the test started the next day, I noticed that in-game, I was a fully clothed chicken! *win!* Hehe ;)
Update: And, because the clothes are labeled 'Testers', they change every so often, which is why you'll often see me modelling pre-release clothes. I hope the devs don't mind ;)
Oh, I love your current outfit. (haha current as of "now"--it may change "soon") Silly, but I love virtual clothes. I spotted an unfamiliar outfit in one of the online articles too, hope we see some new ones soon. Its something to do between tests!
