Vintage style dress

BNWT adorable vintage style dress. Poly spandex blend gives lots of stretch. No flaws. The tag says 12. But there's no way. it's definitely between a 6-8. and a size S-M. There's stretch, so if you are these sizes,feel confident that it will fit. The dress sits just a teenie bit off the shoulders and goes below the knee about an inch or two. I just love this dress, but it sat in my closet and never found the perfect time to wear it.
