Thanks for the photos. All 3 are gorgeous bags. As I think I said earlier, I swoon for the MTO - my personal HG bag. You indicate that all 3 might be a stretch for you right now, so here is some feedback for your decision-making:
The chocolate bag with the pinky/lavender wash appears to be in the same colour family as the new caramel colour with ivory wash, that is, earth-tones. Only you know if they are distinct enough to have a unique place in your wardrobe.
Thing is, Delvaux is always going to come out with new colourways and new treatments for their exotic bags to tempt you. If you’re building a collection of exotics, you might want to wait until a new model that is really different from the chocolate and the MTO appears.
Again, all 3 are very beautiful.
Good luck deciding!
