I have two questions. I ordered a medium fan Canada World Cup jersey but I was stuck between a M and a L. I am 5’8 165 slightly muscular build. Do you guys think it will be too small and I should’ve went with a large or I will be good? Preferably would like to have a bit of room. I am also wondering how I get QC if I just have an account through email. Will they email it to me?
