First of all, this forum is soooo great. I'm so new but I have learned so many things. Thanks so much!! I haven't decided which bag I will buy. At the begining I was in doubt between First and City, but then I found the Box the perfect (between) size for me. I read so many threads here that now I'm thinking about the Twiggy as well. I have read some threads but I still have some doubts. Can you guys help me, please? 1. Which color gets permanent water stains? 2. The veins and the extra shine do go away with use? 3. Does the Box has corners? Is it too boxy? When you carry it on shoulder does it slouches over? 4. I heard something about the strap. What it is about? 5. Which one is bigger: Twiggy or First? 6. Can i use the First for everyday use? 7. FINALLY: WHICH ONE (FIRST, CITY, BOX OR TWIGGY) SHOULD I BUY?
