This combo of a denim shirt and blue skinny jeans is extremely easy to do and so comfortable to rock as well! To add a bit of zing to your outfit, add a pair of black suede derby shoes to the mix. This combo is an excellent idea when it comes to a kick-ass look that transitions easily into fall. If you're often not sure how to dress appropriately for your age but also look fashionable, this pairing is a great illustration.
