Up until now I have only purchased Cities. I love the size, and I usually have quite a bit in my bag. I am considering a Twiggy, but have never seen one IRL. I know the measurements, but it's still hard to decide if the size is comparable to a City and I'm also concerned that a Twiggy might be too "Boxy" or flat and bulky? Can someone who has both give me an opinion? Thanks.
