Vintage 80s/90s GAP Jeans Button Front Denim Dress

This is such a great dress with timeless classic button front. It has a very flattering fit, with the princess seams front and back. I have also worn this as a long jacket. Very cute! Size tag shows size 8, but it fits more like a 6, so I listed it as 6/8. Please judge for yourself based on the measurements below. Pit to pit approx 18". Shoulder seam to shoulder seam is approx 16". Length measuring from base of collar down the back is approx 35".
