I’m not sure what brand that is. (It won’t come up on google) When you put the tinsel in you can’t pull the knot really tight or it will snap. It’s made out of thing plastic so you may have to practice putting it in. 

This tee shirt?

It depends on which kind you want. You can find the types and where to buy them here. 

Aw, I am so glad I could help you out! It looks amazing on you! 😀
