The weight of breasts can vary significantly based on several factors, including tissue density, body fat composition, and overall breast size. However, we can estimate the weight of 38GG breasts based on general guidelines.

A widely cited estimate suggests that a single D-cup breast weighs between 15 and 23 ounces (about 425 to 650 grams). As the cup size increases, so does the weight. Given that a GG cup is several sizes larger than a D cup, we can use a proportional increase to estimate the weight of 38GG breasts.

Estimated Weight of 38GG Breasts:

• One breast: Approximately 3 to 4 pounds (1.36 to 1.8 kilograms).
• Both breasts: Approximately 6 to 8 pounds (2.72 to 3.6 kilograms).

These estimates are general and can vary depending on the individual. It's important to remember that breast weight can have implications for comfort, posture, and physical activity, which is why well-fitting, supportive bras are crucial for larger breast sizes.
