can i take in tshirt shoulder by the bottom?

hi the tshirts shoulder seam is at the bottom so if it take it in there will it look different on the top of the shoulder?

my tshirt is oversized and the top of the shoulders are a bit too big and boxy for my liking. I wanted to follow the seam already on the shoulder. is this possible? if not what would be? thx!! I wanna take it in an inch btw
