Almost finished suit, we are shortening the sleeves a bit and the back of the jacket as it is too long.
I think you're right to shorten the back. Seems like something is going on with the balance and also some horizontal ripples. From the front it looks great so if they can clean up the back, I think it'll be great.
^^ The back has been cleaned a bit after pictures but I will ask the tailor to loosen up the jacket a bit. I don't know if it is a balance issue, I think it might be just a matter of shortening from hem. Here is a back picture.
