Wolf, I think that’s probably your best line I’ve read so far. ROTFL!!!
Seriously, though, some people consider it time for girls to be tznius (whatever their guidelines are for that) at the age of chinuch, so they don’t start until around 6 or 7.
I know that here in Yerushalayim, among the natives it is much more common to start at age 3. I bought my daughter new dresses (to replace her short-sleeved ones) and tights to wear for her third birthday and made it a little more celebratory than looking at like a punishment or hard or difficult or anything like that. It’s definitely easier once they’re young to keep going in the same way, but it definitely depends on their personality. I have one daughter who insisted on wearing socks above her knees at a certain age rather than tights. I was hesitant only due to my concern for how she would be pulling them up during the day. I was right, she has been seen to pull them up while showing her knees and all. She doesn’t do it in front of everybody but there’s definitely room for improvement.
