When I think of timeless, I think of particular colors like black or brown. I don't think of a particular style. I used to prefer the neutral colors like these, but now I prefer the colors that I own. I like the pop of color with watermelon, electric blue, raspberry, aquamarine, mandarin, summer blue (all MK colors) and the non-MK colors I have in light pink (can't recall the name of this shade right now), red garance, and red canyon. I have sold most of my neutral color bags and only have one black (with raspberry interior), steel grey, and tigers eye (brown) now. They don't get used much at all though!
Wow a different perspective! lovely colors too.
