Caution Fake

I've ordered in size 38 me this vest.
It says in many reviews that it fails very small, I was previously in an Adidas store and have them tried in size 38
She was perfect.
And the vest is sold here does not fit! She falls much smaller !,
the logo is much harder from another Kunstsoff, the vest does not shine, there is a brighter black, and the strips are much thinner.
I'm not sure if this product is from original Adidas.
In any event, my back!
