Magic Jacket Help

I’ve just finished knitting a magic jacket if you’re familiar with this, the back is fairly short compared to the front , does anyone know how this should fit? Thanks!

Do you have a link to the pattern or a picture?

Another problem I just lost the pattern, I learned 1 lesson always copy it! I’m going to see if I can find another one. Thanks!

If you get another one, please don’t post the whole pattern here. Just a picture.
