I think I can tell the difference.
Just returned a mini Ginny. The Ginny is a bit cheaper than mini Vara.
In Ginny, the chain is not detachable which means it is also not adjustable, and too long for me (I am 168cm) so I have to return. While Vara is much more versatile with the detach chain. I read somewhere that you can get one more round in the chain to shorten the Vara drop.
And Vara sets all compartments and slots and small purse inside for you, totoally like wallet, while Ginny is only one larger compartment.
