why do girl groups wear this?

The real question is why don’t you wear it lol.

Some cultures are more modest than others. Even when sitting GGs like to drape a blanket over themselves.

Flashing undergarments may not be a big to deal to some. But it is for others.

Most of the time stage is higher so fans are down and can see under their skirts or whatever so it is not just falling.

Also, for most countries, it's not okay to expose too much which is understandable.

THOSE ARE CALLED SAFETY SHORTS FEMALE IDOLS USE THEM TO HIDE THEIR BALLS.
