I was actually shown the upcoming colors for another bag, and my SA accidentally 'over-swiped' so that's how I saw the colors "accidentally".
Don't think I have another chance to see them though I think yellow-brown combination will also be some kind of neutral with a pop of color, you definitely have to try! Here they'll be bringing Spring collection at the end of November, can't wait!
I saw a couple of reds on the other bag, so perhaps also a red (or multicolored red) for the Big Bag?
Don't you hate the suspense
