What height/weight do you think correspond to the different Bbags?
Do you think a person can be too big for a first or to small for a work? I know a person can choose whatever but what guide do you set for yourself?

there are no rules! you bag should make you happy. wear any size whenever and wherever if YOU personally feel comfortable. i have a first, twiggy, citys, works and weekenders and love them all!!!go for the one that calls your name....

I agree with chauss...different bags for different moods....they are all
gorgeous, I have several sizes/styles as well
