If i say girl's clothes are the reason

then it will be wrong...

But both

narrow minded people & clothes is the reason. ....

Now girls will abuse me on my thinking...

And call me old fashioned...

Now let's take an example

If  a simple selfie of your(girl's ) face

make the boys sting....

Then What will happen

if your body is half naked ???

Girls look more beautiful when they cover up their body...
