Help with style as a tall slim man

Afternoon all

I am 6'4 and 80kg athletic build and I struggle to find clothes that fit me right, I feel a lot of large clothes drown me and my shoulders a little whereas medium is often tighter around the chest and short in the body

I have a similar issue with trouser cut, the straighter looser trousers tend to look a bit baggy on me, more so than I would like anyway.

Does anyone have any tips on where to find inspiration for what might look good on a similar body type/ places that may be good to buy for this

Thanks
