Resizing a band tshirt

My kiddo is a drummer and his favourite band tshirts are $45 in kids sizes, but the men's sizes are $11.

So I've used the measurements on his Kiss shirt to cut a pattern.

And put it together ready for his birthday.

Hey, if other artists can make things from ironing boards, I feel like I can cut up perfectly good band tshirts, and feel very brazen about it! Lol/
