To pull together a laid-back ensemble with a modern twist, you can easily opt for an aquamarine bomber jacket and black skinny jeans. When it comes to shoes, go for something on the smarter end of the spectrum and finish this look with brown suede derby shoes. When it's one of those dreary autumn days, sometimes only a neat outfit like this one can get you out the door in the morning. And if we're talking casual clothing for 20-year-old gents, this getup is perfect.
