Do chest-focused strength training to improve chest muscle tone and appearance
Maintain good posture to make the chest look fuller
Wear a well-fitted bra or padded bra for an immediate visual increase
Consider hormonal changes only under medical supervision
Discuss breast augmentation options with a qualified plastic surgeon
Discuss fat transfer breast enhancement with a qualified plastic surgeon
Avoid unproven pills, creams, and supplements marketed for breast growth
See a healthcare professional if breast development is unexpectedly low or has changed suddenly
