Pingson, that's a grey SC? Have we had a grey SC Friday challenge yet? Gray SC on top can be a puzzle. Dirnelli on tumblr has been challenged by this for one of his gray check SC recently.
I like the idea of off white but not too yellow for trousers with light grey. Less butter and more half and half if that makes sense (coffee creamer for you across the pond). Not sure where the cream trousers you have on lie
In that spectrum.
I would go with lighter brown shoes though.
The SC is a kind of olive green with blue/brown and cream over checks - here's a close-up photo with slightly better representation of colours:
Agree on the lighter shoes though....
