I asked that question some time ago. We know that they have spent a lot of time outside - picking fruit, enjoying nature, etc. and that they are looking forward to the freedom of going to restaurants, etc. Certainly they aren't going to want to be cooped up a lot, so there will be some external exposure. I'm also guessing that up until now they haven't had much choice in things like haircuts. So it would have made sense for them to start experimenting with new looks and such. And their guardians might have suggested or encouraged such things as a matter of security. If we saw the seven adult siblings walking down the street on the way to a restaurant, would we recognize them, based solely on the limited (and dated) pictures we have seen? Especially if they did get new haircuts, make overs, etc.
