Size 5T Toddler Vest Pattern Needed

Hi knitters,

I am looking for a vest pattern for a rather big 3-year-old boy. He wears a size 5T. I’m just looking for something simple with only knitting and purling (no cables!), and preferably top down. I guess I could even do a sweater if it’s top down–I’d really prefer something that knits up in one piece (like the Tiny Tea Leaves Cardi I’m currently making).

Thanks for any help!

Something here might work:
