The one with 2 handles? How about the white jumbo with new chain?
I have not seen too many white bags lately, but I saw the white Envelope flap style bag at Bloomies/SCP, try Calling any Chanel maybe they can help you find one. Good luck!
I saw a white or more like offwhite expandable flap at Neiman Marcus in San Diego yesterday. I don't remember if it was single or double straps.
The Neimans Tysons Galleria has the expendable white with 2 straps. The new chain jumbo classic only came in off white. ask for fresh. she works in chanel at Neimans and knows her stuff. 703-761-1600 ext 3245. Good luck.
