Duncan halter denim dress from Show Me Your Mumu! Worn once and got many compliments. No flaws. Runs a little small. I’m usually a size small in this brand but glad I sized up to a medium. I am usually a size 4-6 US in dresses and I’m 5’2” for reference. Material is 92% cotton, 6% polyester and 2% spandex. Retails new for $164.
