I'm sure Vass can do pretty much anything if asked. I would note that the vass in the photo has two major differences from the G&G in terms of the pattern. The straps on the G&G are close together and absolutely parallel, and you will notice that there is a continuous band of contrasting leather around the throat.
Why have Vass copy something from somebody else? Why not have the maker who designed it do it? It's the right thing to do, no?
Wanted Vass to do it since I've nailed my sizing in their U-last. But you are right to a certain point. I may try out G&G after this, especially for this particular model.
