I stopped into Neiman's the other day and decided to try on the tote for fun...and instantly fell in love. I purchased the dark beige and it really goes well with everything. I've tried it on with dresses, jeans and skirts in both light and dark colors and it's absolutely gorgeous. I was curious about the dark white (it looks beautiful in pictures), but the color is sold out at Neiman's SF, SF Chanel Store and Neiman's in Palo Alto (CA). From what I've been told by SA's at Neiman's and Chanel, the dark white was the most popular, followed by the dark beige, dark brown then green--at least here in the Bay Area.
Dark brown is very rich and I believe would be perfect for Fall. The beige I think is more versatile, but you really can't go wrong with either color. They're both beautiful!
Oh, and I recently tried on both the black and white Sharpey totes--they're gorgeous, but very delicate. And after Jill's experience, I think we now know this would be an extremely difficult bag to maintain. The Bubble Quilt collection is not as fragile!
Here is CHANELboy's thread on the Bubble Quilt collection--he has photos of people modeling them, perhaps that will help you in your decision:
