Easiest Transformer costume ever and I need help

[SvK]

Because of the new Transformers movie, and because he mostly wears real clothes, I want to make a Spike Witwicky costume.

I'm not sure if his hoodie is something that was actually sold, or if it was made just for the movie. Let me know if you recognize any of these logos and point me towrds the source.

The front has a big "A" with "G" "ST" and "R" piled around it. There's a tag on the bottom hem bearing a shield-shaped logo with "GS" inside.

I can't find a nice picture of the back. It is obscured by the hood, even when it isn't obscured by motion blur, flames, or angry robots.
It's got some round white thing, "S" and "01"

You´re right...G-Star is a brand.

G Star Raw, I think it is a UK brand.

G-Star is apparently too uppity to actually sell their clothes on their website. It's all Flash and nifty transitions and fancy pictures. That probably means the clothes are ridiculously expensive, so it's just as well that I can't even try to buy them.

I don't think I could forge the hoodie from a plain brown one without a good look at the back, so I'll probably go for his other outfit.
