@nonaffiliated In my opinion as long as everything is framed with a positive body image you be you. Give her the chance to be her. 41m here. I've had some real major ups and downs with my body. I may not have been happy to show it, but in circumstances where I was less clothed I didn't hide it. I did ask them for privacy. They've seen my loose a lot of weight and try to avoid hoodies to hide in. So now they went from seeing me avoid skin to being comfortable in a Tshirt or even less.
We tried to couch it in respect. Their body is theirs. They are welcome to make the choices that make them feel good. Wearing this and liking this style of clothes vs not liking x style of clothes or preferring to be less garbed or more garbed.
My son prefers shorts. I don't. My daughter prefers dresses or long pants or really comfy shorts. My ex wife has different tastes. My son liking shorts would complian he was cold when the ac was on. We would explain it's tx, you chose to wear shorts, we aren't turning off the ac, adapt to your style of clotheing (is get a blanket or wear different clothes for the right environment. The world isn't going to warm up just because you want to wear shorts).
In the end we want them to be happy with them and their body.
My daughter is approaching teens, so for me especially as a male I've backed off a lot. I make sure to knock on her door always before entering. I let her know if I would like a hug or let her make the first move for most physical affection. That's both a part of her personality and her getting older.
I will say this. I think we've had success because when they need to shower they will walk around the house full in buck naked for like 10 minutes, whether the blinds are open or not. No matter how much I ask them to pay attention.
That could be a situational awareness issue, but I'll take it as innocence and body positivity.
If you are helping them have a bed rock of body love and self positivity, then let 'em swing!
They will likely let you know if/when they need some changes.
