Semi Sheer Bat Wing Caftan

This is a homemade dress, or caftan or cover-up. I’m actually not sure what it is. The fabric has some texture to it. It’s a very odd fit – I would call it a size small for someone at or below 34-28-36. Single back hook/eye closure. Given the bat wing sleeve, it is near impossible to accurately measure, but it’s roughly 36″ across the chest and 40″ long. Lavender/blue color. Very good condition.
