I've had a cheeky look around and you can get this look quite easily, again approximately £300.
Also I promise the next one won't involve Paul Weller.
The main event in this particular look. I suspect Weller's would have been tailored, but for those of us of more modest means, this is a good recreation. I've got one in navy and it fits well, looks great.
Weller looks to be wearing some standard black suit trousers so you might as well make 'em a good pair. As the Ivy Leaguers used to say, natural fibres always look the best.
However, if you're looking for a more cost-friendly option, CX London do a black pair of Sta Prest for less than 1/2 that price.
Classic Jam, probably not what you'd wear down the pub but I'm sure everyone's had a pair at one point.
IKON do a decent pair for a decent price.
Price: £1.80 (5 pack)
Very much a Mod revival thing, the white socks are a classic accompaniment to Jam shoes. But you hardly ever see original Mods (1960s) wearing them.
Nowdays they're super cheap so you've got no excuse not to have a pack handy.
Hard to see what he's actually wearing under his jacket so I'm going with a hunch here. FPs are always a bit pricey I'm afraid but I imagine a decent shirt would do just fine for this look.
