The OP is most likely a brit dude as well - we're a funny lot over here

I'm sure he's Dutch or German, at least in background ... has the typical slant on English grammar and spelling.
Personally, I kind of like the look.
And the shoes are good ... very casual touch, and nothing wrong with that, depending, of course, on the kind of party.
The look is just slightly tarted up, in a good way, by the 'waistcoat,' um, vest.
Of course, as midlifebear notes, it's not really a suit.
I suspect the OP's kind of an individualist.
(Disclaimer: Of course, I have no real clue ...)
