Hill House Athena nap dress, size small, missing string, Matilda print

Hill House Athena nap dress! Size small Matilda print, light blue and maroon One of the strings in the back has fallen off. The dress could be easily fixed. It can still be worn, but it feels as though the sleeves are falling off. I have worn it since the string fell off, and it was fine but a little annoying. Otherwise, in good used condition with only one very small stain on sleeve (shown in picture).
