Is wearing unbuttoned jeans weird?

mrsingle
I think this would apply more for girls as my sister does this.

Her stomach fat makes her belly stick out post pregnancy, but the rest of her body is thin. Her jeans fit everywhere but her belly makes an odd fit. Very often she cannot button her jeans fully because of her big belly, sometimes she will put a belt over the button to hold her pants up but more often she cannot and being unbuttoned her pants keep sliding down. When unbuttoned the pants make a small bulge under her shirt. She constantly has to wear pants not buttoned fixing them.

Is this weird or do others do it? Any ideas how to fix this with her situation?
