This is actually not a nun dress. Not even a dress at all. This is a latex leotard from Westwardbound and I really like this one. After looking at hundreds of dresses without finding the perfect one for my nun outfit I started looking at leotards instead. This is just the right one!
Now remember that this is just the top. With my new skirt from Libidex this would look like a long black gown. Adding the cowl and veil would make it a nuns uniform. Adding a hood, long black gloves and high stiletto boots would make this into a complete latex nun. Then I would only have to find a nurse cap and nurse armband to give it a clinical look.
