Colorful Print Sleeveless Dress

Eye-catching colors. Bright reds, oranges, yellows, blues. See pic #2 for closeup. 17.5" armpit to armpit. 33 inches from shoulder to hem. Based on armpit to armpit, I don't think this would be too big for a size small. 92% polyester, 8% spandex- lots of stretch. No tags, but new/never been worn.
