girls have to cover a lot and there are diff recquirements for everything. some have to be covered and cannot be too tight (ex legs, stomache..) and some have to be covered but can be as tight as u want (ex arms)and thats why shells can be skin tight cuz only has to be covered not loose.. and some can be tight and transparent but should be covered (legs below knee).. got it? if u want more info read rabbi falks book.. its RLLY machimir on e/t but has the right ideals and approaches for a torah jew..
