Is it because of the bra or the shirt, or both?

For one her shirt is too thin she should wear maybe a spaghetti strap to help minimize showing her bra line. 2nd she is wearing a padded demi bra the reason why the bra line is showing more a thinner bra would help minimize however it wouldn't necessarily give her the lift she could use. I would suggest she would wear a full coverage padded bra with a spaghetti strap under. A full coverage body by Victoria bra that is padded this will give her the lift she needs and more support1
