hi guys, can i know how can i tell if a jersey is fake or original?

im looking at liverpool jersey.
i checked over with adidas store, S size adult jersey is a little too large for me.

after a long checking here and there, i found out, i can actually go for a junior XL kit [176CMs].
but when i check with liverpool official store, they doesn't have this size, they have only junior 13/14 years junior kit, and that is junior L size.

my concern, if the junior XL which i found in malaysia is a fake or original jersey.

one more question, anyone get any jerseys from local store, Al-Ikhsan before? do they sell original jersey?

there's a jersey thread available.ask anything about jersey there.

ah, okay. thanks
