Nothing says fall more than a green military jacket. I picked this one up at a J. Crew warehouse sale in Virginia 6 years ago and it's still one of my favorite pieces when the leaves start to change. This jacket could headline a thousand different outfits, but for this look I decided to compliment it with double denim. The key here is creating contrast between the two denim pieces, not trying to match them. Dark denim up top and light wash jeans would work here as well, but the point is there needs to be a stark difference in the two washes, otherwise it will look like you could only find one sock and grabbed the closest alternative to fill in. Finishing off the look with a simple pair of gray high-top blazers keeps the focus on the contrasting denim and sharp military green.
