You'll be amazed at how super easy it is to put together this polished outfit. Just a white sweatshirt matched with brown dress pants. A pair of white canvas low top sneakers can immediately dial down an all-too-polished getup. This one is a viable choice when it comes to planning a knockout ensemble for summer-to-fall weather. As a man in his 30s, you probably want to start dressing maturely. If that's the case, combinations like this are ideal as inspiration.
