Vintage Military Style open back mini dress EXCELLENT condition

I haven’t been able to identify what year this dress was made but I purchased from a vintage resale shop in Missouri in 2007. This dress SERVES, it’s very short and a little stiff but it holds you in and lifts you up 🥳 Single high button in the back at the top, then a cut out open-back look down to the hips where the dress starts to flare. Looks especially cute with cowboy boots or converse low tops! It is definitely tight with very little give though. All buttons are functional, not decorative, the arm button creates a subtle poof that is very commanding. Size L (vintage so closer to a size 6-8)
