In my family teenage girls dress up if they want to but not to shul, or outside. just at home and at the extended family meal. (which at this point is in a hall since nobody has a home large enough to accommodate the crowd.)
The year I got married, my sister a teen at the time dressed up as a man, in my new husbands cloths. She came into my parents dining room and walked right up to our father with outstretched palm for tzaddakah. (she didn’t open her mouth as her voice would give her away.) Although she didn’t have her face covered her tatte didn’t recognize her. That was a laugh.
My teenage girls like to put on big hats, long queer earrings (one looks like a bug…) and such stuff.
