Stunning One of a Kind Gray Dress, Size M

Light and airy 95% rayon 5% spandex gray dresss bought at boutique in NYC. Paid $200, I never wore it, just tried it on a few times and it has stayed in my closet. I do see there is a couple threads coming loose but I reflected it in the price (I'm probably being too exaggerated but I like to be very honest in ny description). It is too short on me to wear to work. I am 5'9 and it comes to my mid thigh.
