Make a jaw-dropping statement anywhere you go in a denim shirt and dress pants. Dark brown leather casual boots will give a fun feel to this ensemble. In winter, when warmth is everything, it can be easy to settle for a less-than-stylish ensemble in the name of practicality. However, this ensemble is a vivid example that you totally can stay toasty and remain stylish during winter. Overall, a good example of 20-something fashion.
