The following is my humble opinion:
Boys and girls should not be doing what “everyone else” says is correct like not wearing sweatshirts or shaving every single day.
Personally, I want to marry a guy who does things according to halacha and once halacha is met he should feel comfortable doing whatever he wants regardless of what “everyone else” says.
We are creating children who are not comfortable in their own skins. A girl who feels horrible about herself because she wants to wear a sweatshirt and chas v’shalom wear her hair curly one day instead of burning her hair to death with an iron. A boy who doesn’t feel like shaving every day and when he is playing basket ball wears a tee shirt. O my goodness people… chill!
