Weight Gain: Begin a weight resistance program to gain weight and as part of your workout you may benefit from bench presses and other chest exercises. Consult with an exercise physiologist for a plan that will help you gain weight in a healthy manner. Best wishes.

Eat healthy: You don't need to gain weight. You can improve your appearance by exercising, especially weight training. Increasing the muscle mass of your chest will make your breasts appear larger; then there will be no need for weight gain. Stay thin; in the long run it's better for you.
