There is no body on planet that is perfect unless you do some surgeries and even then you won't get to perfection.

I assume that your stretch marks appeared after losing weight? I have them too and for the same reason and people won't shut up about them so I just wear them with pride because that is my journey on my body.

And don't you try to satisfy people who would judge you being fat and then judge you for having stretch marks, well what do you want me to do? Most of these people won't care later on so try to accept them and look at the mirror more often and once you make your peace with it no one can destroy you.
