A grey knit blazer and a navy polka dot long sleeve shirt are the kind of a fail-safe combination that you need when you have no time to plan out an ensemble. And if you wish to immediately ramp up your outfit with shoes, why not add a pair of grey leather double monks to your look? So if it's a boiling hot day and you want to look sharp without exerting much effort, this getup will do the job in no time.
