Athleta Sleeveless Maxi Dress

This is more like a dress in a dress! The exterior sheath dress features a long slit on the left side (as you're wearing it) that starts about 7" below the armpit and then goes about 39" in length to the ground. The total length of the dress from the shoulder to the ground is about 53". There's an "interior" dress that peeks out from the slit and that dress' length is about 33" from the shoulder. The size is XS and the color is a teal blue. The fabric is 65% tencel, 28% polyester, 7% spandex. Machine wash cold, gentle cycle; tumble dry low. Excellent used condition. I've included two pictures to show the dress color in direct vs. indirect sunlight.
