Free People Marci Gras maxi dress - size XS

So cute! Halter neck is adjustable as is the back (ties for a perfect fit). Would make a great beach/pool coverup too. Worn only once. It’s a XS but in true Free People fashions runs big. The ties at the neck and back mean you can customize it to your body so I’m guessing it would fit up to a M. Leg slit on both sides. Slit hits me at mid thigh and I’m 5ft8. A few imperfections pls see close up photos. Hem is a bit dirty, haven’t tried to clean it though.
