Find me Spike's shirt!

My brother has recently gotten into Buffy the Vampire Slayer and has expressed a strong desire to own the nifty sort of shirt Spike wears all the time. It’s a long sleeved collared shirt, red with red vertical stripes and black buttons. Would prefer a version without pockets but can always dismantle them. Examples here, here, and here. Can anyone help? My google fu has left the building.

If no one has an idea of where to find the shirt, maybe you can help with my search terms. Is there a particular term in the world of fabric to describe a fabric like that, where it’s all one color but there’s an obvious pattern like stripes?

“Red on red”? “Color on color”?
I don’t know much, but I didn’t want to leave you hanging.

Not sure where you’d find them but the first two and the last are not the same shirt. Different colours, different material… I swear I’ve seen something like the last one somewhere and I’m looking now. The first one looks like it could be similar in style to the dragon shirts (minus the dragons I’d say) that were so popular a few years back.

Sorry I’m not much help right now.

Bowling shirts, they were very trendy.

Forget the shirt, can I have Spike?
