Denim Dress - Stefanel, Italy

I purchased this dress at the Stefanel shop in Como, Italy. Very cute, long denim dress. Hidden button down front, collar, side pockets and ties. Dark blue denim. There was never a size tag on the gsrmet but the sales tag pic is attached showing size XS. Wore 2x. In great pre-owned condition. This ran a bit large. I am a 4-6.
