Anyway Weller's outfit in this is on point as usual. To clarify, I'm not sure why I'm not bothered by Bruce / Rick... they just don't seem to nail the look in quite the same way.
The foundation of the look is a smart black button-down. Surprisingly difficult to find these anywhere reputable. So we've gone with Ben Sherman.
I still prefer these over the alternatives (e.g. Sta Prest from anywhere else) because they Adaptor's ones have a better feel to the fabric.
This is a bit trickier as the exact blazer Weller is wearing doesn't actually exist anymore. Best bet is Madcap England, who do a variety of quite loud and zany jackets. You can get this one on the Atom Retro site.
Thanks to the cameraman getting a great shot of Weller tapping his foot in the video, we can surmise he's wearing a pair of Bass Weejuns. What else, frankly?
