This very same problem is being discussed on another site. I've been wanting to make one for Ruby. I will try and get one finished today and let you know if it works. If so, I could make you one. I'll let you know later for certain.
I have in mind something made of satin, like the top half of a ladies dress slip or a camisole, is that the same thing you had in mind? Or, was it more like a wife beater t-shirt?
