Problem with shirts’ fitting

Hey guys, I’ve got a little problem with wearing shirts, which I wear daily to work, and my problem is that I have wide shoulders and a pumped chest, but a slim waist… and when I’m wearing an L sized shirt, it fits perfectly on my waist, but looks terrible on the upper body, since it tightens on my chest and looks awful. But when I’m wearing an XL size, while being good on shoulders and chest, it looks baggy on my waist, making look very unfashioned and fat…

So I wanted to ask you guys for help… also sorry if it’s a wrong sub to post this
