If it is mainly for taking pictures or looking good, it may be more appropriate to buy a bigger jersey, because it looks more comfortable, more casual and more lazy. In this case, the jersey will be easier to match with pants, whether it is loose or tight.
But if you pay more attention to the practicality of jerseys, such as wearing them during sports, you should buy jerseys that fit you better. Because jerseys need to provide enough flexibility so that you can be unrestricted in sports. If the jersey is too small, it may cling to your body, which will not only limit your sports performance, but also lead to some safety problems. In this case, there may be some advantages in buying a larger size jersey.
In short, whether to buy a bigger football jersey depends on personal preferences and actual needs, and you can make a decision according to your own specific situation.
