Hi all! I am trying to decide between the twiggy and the purse. I have the purse style and I love it but, because it is flat, I have to be careful about overstuffing it. I have never carried a twiggy. Just wondering if anyone has both and if the twiggy carries more, less, or about the same as the purse. (I also have the city so if someone has the twiggy and the city, the same sort of comparison would be helpful--more, less, about the same). Thanks!!
