I agree 100%. I understand that Meghan likes darker, more muted colors and really isn't a prints lover and that's entirely fine. But, we've already seen her look lovely in dark green, gray, and black/white combos. Any one of those would have been a beautiful choice for the Christmas walk. Nothing flashy, nothing printed, still in her favorite muted shades but not so drab and somber and meh. I absolutely hated the bag and the boots didn't work with the outfit, though they would be lovely with some slim-fit pants and a nice blouse for a relatively casual engagement. The very dark colors just didn't work and the open coat looked sloppy. Granted, I really hated last year's look and this year's look isn't really any better but it is different in a good way.
As for choosing these super dark and drab outfits constantly as a way to blend in....I actually think it's exactly the opposite. If she were trying to blend in with the environment and the rest of the family, a dark green or that beautiful gray coat we saw earlier with the wide-brimmed hat would have been great choices. As it is, by making herself a topic of conversation in always wearing dark and drab even when others are in various shades of color, she attracts attention (and not in a positive way) to herself. There are ways to walk that middle ground and sticking with shades like dark green, gray, or even white/black would have done that beautifully...still fitting in with everyone and the environment without calling attention to herself if that's really what she was trying to accomplish. As it is, she again stuck with the dark, drab, couldn't possibly be anything but navy or black and is again seeing negative comments regarding how somber and funereal it looked against the reds, greens, and lighter blues of the rest of the family.
