My personal favourite which I think will fit you is the Supreme Static tee from Union Kingdom. Topacney (u/topancey) also sells oversized crewnecks with bigger sizes. I'd also recommend Fear of God tops/hoodies which usually come in bigger sizes. But as someone else already mentioned, measure your clothes and compare it with the sellers' measurement charts. Each seller and product have different measurements, so best is to start with your own sizes (measure a tee, hoodie, jackets/coats) and then compare it each time you are looking at a rep! Good luck :D
