Marry a grey sweatshirt with a white dress shirt if you're going for a neat, dapper look. Beige athletic shoes will easily play down a smart look. There's nothing like a killer ensemble to cheer up a dull fall day. The ability to pull off outfits like this is one of the benefits of going into your 30s.
For a smart casual look, pair a grey sweatshirt with a white dress shirt — these two pieces work pretty good together. If you wish to easily dial down your ensemble with one item, why not complement your ensemble with brown canvas low top sneakers? This one is a viable option when it comes to piecing together a standout outfit for weird transition weather. As a 30-something guy, you probably want to start dressing more like a mature gentleman. In this case, ensembles like this are ideal as inspiration.
