I usually build my outfits to fit one main piece of clothing. This time it was my MINKPINK double-breasted cropped vest that I got in Montreal 2 years ago. I wanted a military theme too, so I chose my colours according using army camo as a reference: Grey, Green, Black. I think the end result looks pretty good! Casual, not too army, and still girly. I think the boots add a nice touch.
