A pretty basic outfit but one I've been reaching for quite a lot recently in that weird 4-seasons-in-a-day type weather that we've been having a lot of in Manchester recently (also known as, 'summer'). I've been going back to that failsafe jeans-and-blazer combination more so than usual really which is probably more a sign of my laziness and lack of creativity at 6am when I'm stuffing clothes into my gym bag pre-office more than anything else, but let's pretend it's a style thing. 

Mixing up a few different colours (black, dark green and tan) and adding a couple of lux details (a double breasted blazer and cut-out detailing on the leather shoes) turns it into a slightly more thoughtful outfit and one you can get away with wearing to the office, with those after-work drinks thrown in.
