If it's comfort and functionality that you love in menswear, team a charcoal wool blazer with a black crew-neck t-shirt. If you need to instantly tone down your outfit with one single piece, why not add black leather low top sneakers to this outfit? Seeing as temps are starting to drop, this getup is a viable option for the time in between seasons. This pairing demonstrates that as a gent in his 20s, you have a wide range of styling options.
