More second hand: A Joseph suit. I can see that the trosers need ironing.
Crocket & Jones suede shoes
Top half is great, but I think the trousers could stand to be a few shades darker to contrast a bit better with the jacket. Also - and I appreciate this is a bit rich coming from me - I think the jacket might be a half-inch or so too long in the body, maybe.
Nice colours. You know, I saw a near-idently fabric in a Zegna suit the other day. Very nice (would have been tempted if it had fit me better). You have a real eye for finding good vintage items.
Great personality in this outfit (the colour scheme, the shirt fabric & monogram, etc). Really great.
Even so, I'd suggest double-checking the trouser length (while wearing braces) at the final fitting.
The suit seems fairly typically English in style, and not particularly FU. I like that style of suit though. I'm not convinced the colour flatters you, but that may just be a combination of the mint shirt and the artificial/interior lighting. It looks taupe/olive here and that's a tricker shade to wear. A richer/darker green or brown tends to work better on many skin tones I think.
