The sizes for this raglan pullover pattern are either a four or six. I think the six would be the closest size. You'll want a little room for growth. This is a pattern from a sweater wheel pattern generator. You will input the size you want and the yarn type. It gives several variations for the raglan sweater such as a pullover or cardigan. It also gives directions for different necklines.
