Mod Ariella Dress in Blue and Yellow

Cute, fun dress. Never worn! Three-quarter sleeves and tie around waist. The tag says size Large, but I bought this dress because it fit me and I usually wear a small to medium size. I've noticed the Ariella brand runs small. So please look at the measurements for the best sense of if this will be a good fit for you. It's light and loose, so would probably fit a range of sizes. Pit to pit - 19" Length - 33" Arm length - 18" I never got the chance to wear this dress, so it's in perfect, like-new condition. From a pet and smoke free home.
