Sai who? Sophisticated and versatile, the Sai Dress by Reformation is equipped for any scenario with its sleeveless maxi silhouette and turtleneck neckline. • Responsibly made with organic cotton • 98% organic cotton, 2% elastane • Pullover styling • Machine wash • USA this is the perfect event dress, and will be a go to for just about any occasion. The dress sells out. It is hard to find, tags are intact, I did not wear this size extra small could accommodate most smalls. Plenty of stretch.
