I just got my Aubergine Sophia but it seems to be kind of different than my black one. My black one has thicker and stiffer leather than my Aubergine one. The Aubergine one is also slightly bigger!!! Is this an issue you gals also see or is this just a problem with my batch!!! Plz help. Photos attached. Notice how the Aubergine slouches already even with stuff inside and the black one stands firm even without stuff inside.
