Need advice on this style (hobo)....

Yeah, I'm a little late to the 'game' too ... but, the other bag that you should consider if you want a longer shoulder strap, is the new Courier Style (see my thread - CeeJay's Balenciaga bags; I have a picture of my beautiful Cornflower Blue Courier bag!). This is my most FAVORITE bag of my collection (and I have quite a few B-Bags). I love the fact that the strap is adjustable, so it can be worn like a "traditional" shoulder bag or across the chest like a Messenger bag. Extremely versatile ...

Another option is the Messenger bag, however, since it's part of the Men's line, it does not have a Mirror.
