I love it! i just don't know it's made by who....you can see the logo inside the blazer but it's not clear....does anyone know which designer is this?
Then you have poor taste. GBR QED.
It's a madras. I don't think you are going to find the maker, but there are plenty of jackets like that (though you'll need to look harder to find one in that (large) scale and that dark. Still, they're out there. I believe Orgetorix has something similar.
On another aside (because it's fun to rag on people who deliberately make themselves look like that), if you look at their body language, he's clearly striking out.
