I Think I might be getting fat

Is it just me or does this shirt look a little too small. I really hope it is not because i am getting fat or something like that. I think that my sister was supposed to send me one that fits because it is my favorite shirt. I do not think that this is that shirt, but it might be because this sister who said she would send the shirt is pretty responsible and does what she says she will. Now this shirt has shrunk so small that i have to give it away and am without my favorite shirt in the whole world. If only someone knew what happened to its replacement.
