XS Free People Flowy Dress

Loooove this beautiful long sleeve tunic dress by Free People but it no longer fits me :( In pretty good condition with slight pilling at the sides (shown in photos) and a little discoloration on the inside at the back of the neck (can’t see when wearing the dress) Size XS But could probably also fit a small - I’m 5’5 and this dress hits upper to mid thigh on me :)
