A white and black horizontal striped tank and black jeans are absolute menswear essentials that will integrate perfectly within your current styling repertoire. Rounding off with a pair of derby shoes is a fail-safe way to inject a sense of elegance into this outfit. This look is also great if you're looking for warm weather wear to make a slow day more bearable. This getup demonstrates that well into your 30s you have a wide range of dressing options.
