How do I get my avatar shirt for day one?

The day one avatar shirt was available for free for sometime around launch. Its doubtful that it is still available for free but you can check.

The day one achievement should have come inside of the packaging of your xbox one. That is assuming that you bought a day one edition and not a standard edition on day one.

ive seen avatar teeshirts. 1 black saying xbox launch and 1 green that says xbox one. not sure how to get these.

I got my avatar shirt. I was dissapointed it didnt come with avatar day one sunglasses or a dancing day one bear prop. Even a day one avatar bracelet would have been nice. Instead I bought a console day one edition (preorder no less) and all I got was this
stupid T shirt?!! How dare Microsoft. I want back my countless hours of gaming, skyping with family, streaming movies, and not having to get up and change discs every time i want to play something different. You will rue the day you lowered the price Microsoft.
Now in order for me to take advantage of this deal I'll have to sell my day one with Kinect at a drastic loss just so I can get a $349 console without Kinect?! Thanks but no thanks

I saw one of my friends with a day one avatar shirt on his avatar. I was wondering where do I find it because I would like to put it on my avatar.

Maybe ask your friend where they got it?

I once earned enough to get a t-shirt for my avatar
