Shirts for people who work out

Hey! I’ve been looking for a shirt that fits me for some time now. I like to wear loose/oversize garment that drape nicely and I want to feel comfortable wearing my clothes while looking good. The problem is that I’m quite big meaning I have wide chest and shoulders and traps are somewhat big. I’m no bodybuilder or anything like that - it’s just how I’m built + a lifetime of sports. This makes all the shirts I’ve tried fit me super awkward even when sizing up to XL with relaxed fit.. They constrict on the shoulders and I look like a wannabe muscle-guy who’s not really pulling off the tight shirt look. So which brand has TRULY relaxed or oversized shirts?
