My favorite bag EVER which also happens to be purple: Berry Patent Tribeca Tote! I can't rave about this bag enough. It's absolutely perfect. It's light, it's durable, it's easy/comfortable to carry, it holds a TON...for instance, I stayed overnight somewhere for a few days last week and ending up having to put a few extra things in my purse. Not only did I have my normal items (mini skinny, wristlet, sunglass case, eyeglass case, planner, iPod, keys, gum, lip balm, phone, etc) but also put in a small novel, my small make up bag, a reusable water bottle, and one of those little packs of candy bars. Still zipped. Yup...I do also have pretty awesome packing skills, I attribute them to playing too much Tetris as a kid.
I also had to throw extra stuff in there yesterday, so I had the normal stuff, a water bottle, a small sweater (for work), and a magazine. STILL. ZIPPED.
I could go on for days
