I am having trouble choosing between 3 different bags and would appreciate your help. I am looking for a smaller bag to carry my essential everyday items. The three bags that I am looking at are a Speedy, the Pochette Bosphore and the Olav PM. I like the idea of a shoulder bag, but everyone really seems to love the Speedy so what do you think? Oh, I am a woman if that makes a difference in your choice. Thanks!
