The ultimate choice for a knockout and dapper look? A dress shirt with burgundy corduroy jeans. On the shoe front, this outfit pairs really well with brown casual boots. In the winter months, when warmth is a must, it can be easy to settle for a less-than-stylish outfit in the name of convenience. However, this outfit is a striking example that you can actually stay snug and remain equally stylish in the winter months. Surely a surefire option if we're talking outfit ideas for 20-something guys.
