This is just plain stupid. Did she look at herself in the mirror before she left home? Obviously not.
From the picture, I’d guess she doesn’t look in the mirror all that much.
If I wear a tight shirt, I use an ankle holster. I used to carry one a lot in a belt mounted camera bag (Nikon on it).
That said, you can be like Jeff Cooper, who said if he didn’t have clothes that would conceal a pistol, he’d carry it in a paper sack.
