I think i can help you with that, i doubt Chris would sell a non-genuine product tbh. The model stated for this shirt on his website is S3208Q/F. So it probably sounds like a lower end model to me given its the same design as the S2000Q.
You can try the Victor distributor shop near the Eunos MRT station, they have some stock of the S2000Q left, but only in pink. I just got mine there and i can confirm its the same one as the first picture.
Yep, there's another model. But I don't know the specific differences.
It must be a great fake shirt if it's not genuine since it looks very nice. Maybe you should make a better picture with front-view.
But I also doubt that Chris from E-Link would sell any fakes.
