Why not marry a parka with sweatpants? As well as super functional, these two pieces look good matched together. Black and blue athletic shoes are a smart pick to round off your outfit. Ideal if you're in search of some amazingly inspiring relaxed style for 40-year-old men.
We're all looking for functionality when it comes to styling, and this off-duty combo of a parka and sweatpants is a practical illustration of that. A trendy pair of white low top sneakers is the simplest way to infuse an added touch of refinement into this getup. This combination should clear any doubts you had about wearing casual clothes as an over-40 gentleman.
