i'm 5'4 and about 105-110 lbs... i currently own a city and it is great as an everyday bag. Light weight and right size for all the essentials - lv koala purse, small organizer, cell phone, ipod, a bottle of water and a scarf/shawl.
I have tried the work and it isn't too big for our height. It'll be perfect if u tend to carry more than those essentials i mention above. I am currently waiting for an EB Work so that i can carry my gym shoes for days that i am hitting the gym.
do also note that GHs are slightly heavier!
