if i don't have other b-bags then the city definitely would be my first, no doubt in my mind.
i have and had the city, first, twiggy, PT, work, weekenders and city is still my fave in terms of size and shape if i can only have 1
i love the versatility of the handle and long strap, also the preportion, although the PT is bigger but i feel the bag is wider and when i carry it with the long strap it is harder to access the bag through the zipper

city +1

The strap to wear it on your shoulder is VERY handy but my first love is and always will be the work... It's big, it's beautiful and so practical. Just save for a work too and wear them for other occasions.
