That's true, it's hard it is to find a real lether dress, specially for someone taking a slightly bigger size.
There is a lot of choice on Ebay, mostly from Asian countries but I am sure it's probably dog skin or something similar, as it's too cheap and doesn't look thick
If the dress is European, it's usually an "outside" dress, with zips and buttons that make it not very suitable for short appointments which sadly seem to be norm these days.
I would love to have a nice sexy leather dress, tho, regardless if I am touring or not, it's easy to clean, it does look cool and honestly I got sick how many times I have been asked for it, especially in a very very short tour. Of course most people who ask are not serious but I would love to wear it for myself mostly.
