Ittindi Gavaskar has been making lovely prim breasts for some time. I'm happy to say that the other day I saw an announcement that his work will have copy permission.
Why is this important? Because without copy permission, if you wish to customize something, you either have to be, like Mary Poppins, "practically perfect in every way," or be very sure to write down the exact sequence of operations you perform so you can undo them in case you change your mind.
So... a thousand thanks, Ittindi. There's a vendor for his work at Northstar Mall (and probably other places--I apologize for my faulty memory). Do check it out.
