Go for a simple but at the same time cool and relaxed choice by wearing a dark green camouflage military jacket and grey jeans. Our favorite of a countless number of ways to complete this outfit is grey suede low top sneakers. When leaves are falling down and temperatures are dipping, you'll love this look as your go-to for summer-to-fall weather. This pairing shows that as a 20-year-old gent, you have a wide range of style options.
