Better too large than too small like you said. Mine usually fit pretty well. I got a large and it’s true to size as are most I’ve ordered from them. Depends on the make. Nike usually runs big and puma runs small
I don’t think I fully understand your question but the jersey is as close to authentic as I have ever ordered. The fit of the kit is not overly large or baggy. It fits very nicely for a soccer kit
It is basically 1 to 1. You can pick which patches you want on it such as the league and so on. The quality is very close to the on field kits you can’t really tell much difference. I have quite a few of these. I ordered on July 11 and my order got to me on July 26. Very efficient.
