If I’m going to be honest, w/ no bias, this legit looks like a legit Downtown L.A Alley knock off.
I say that b/c of the position, or lack thereof the Adidas logo. It seems/appears especially titled w/o even putting the jersey on. Also the ACC logo is not across, symmetrically from the Adidas logo. Furthermore, the Adidas logo appears stitched, while the U & ACC logos appears ironed on, along w/ the sleeve stripes & numbers.
In essence, it looks like a heavy pro club v-neck T-shirt that stitched the companies logo, hastily, along w/ the main number, but chose to use ironed on plastic for all others.
