I love them all. I voted for the Blake because it is my favorite. I don't have a Venetia, only because I need a shoulder bag and am not great with handheld bags, but it is definitely very elegant as well.
The venetia is the most elegent. It's really lovely, but handheld bags don't work well for me. My favorite is the multi pocket (large) because it just looks great with my wardrope and its so functional.
