This is for my friend Jason, who will forever be Pinkie Pie. ^_^
Edit: I feel like I should edit the description of this. I never thought in a thousand years that this would get so many views. Thank you so much to all of you for your kind words and comments on this!
And thanks to Jason, because if it weren't for him, I would have never drawn this.
Edit 2: A pixel version of this shirt can now be purchased at welovefine! [link]
