A rare photo of me wearing jeans:

You guys already know I don't "do" jeans well, since I normally only wear them in situations where I'm not paying significant attention to how I look.
But I got the pictured jacket just recently and like the way its fabric looks against denim. Since I only had to pop in for a half-hour's work today, I figured I may as well make an honest attempt to use them together in a vaguely smart way. Any & all advice welcomed, even if it's simply to say I should resist the temptation to try MC-friendly denim looks in the future (rest assured, it doesn't happen often!). An equally rare (near-)robopose pic is included to aid the advice process. This is an area where I'm totally outside my comfort zone because the cultural vibe given off by denim, combined with the general cut of jeans, is so antithetical to how I normally dress that I struggle to marry the two.
Stuff I'm already aware of: 1) the shirt sleeves are half an inch too long, 2) another shirt button undone would have probably looked better but as it's cold enough to need a scarf and waistcoat, that's a non-starter, 3) jacket sleeves are not different lengths despite the impression in the photo; it's 'cos I'm slouching slightly to one side rather than standing normally.
