Mascot Short Sleeve Shirt Beibei
Then again, if you prefer to identify with just one mascot instead of all five a short sleeved shirt like this would be perfect. Beibei is super cute! And now you have a shirt that looks like it would be awesome for whatever you need it do (as long as it's casual).
I think Nini is my favorite of the mascots for this games. And this cute little jersey will let me celebrate the games in a way that doesn't have the Olympic rings plastered all over it. Plus that green is kind of awesome.
Though Nini is probably my favorite of the mascots (though I like Beibei too), some people might prefer mischievous Yingying. Yingying's shirt matches his(?) outfit and would be perfect for a little firecracker in your life.
