Gap cool girls sleeveless dress, vibrant sz 8

This very cool a-line dress reminds me of something from the 1960s, like something you would have seen on Laugh-In during that era. The colors are very vibrant and the flowers are a very funky psychedelic flower design. There's a Silver Thread running through this so it's very glittery as well. Fully lined, closes with a zipper in the back. The length shoulder to hem is 29 in. The bust is approximately 28".
