What is the ideal breast shape?

Big breasts do not mean perfection. The ideal breast shape should be an equilateral triangle:

The center of the clavicle is connected to the center of the two breasts, and all sides of the triangle drawn are equal. , then it is the ideal breast.

If the bottom edge is too long, it means that the breasts are too expanded. If the sides are too long, it means that the breasts are sagging.
